Product Description

Virtual private networks (VPNs) based on the Internet instead of the traditional leased lines offer organizations of all sizes the promise of a low-cost, secure electronic network. However, using the Internet to carry sensitive information can present serious privacy and security problems. By explaining how VPNs actually work, networking expert Jon Snader shows software engineers and network administrators how to use tunneling, authentication, and encryption to create safe, effective VPNs for any environment. Using an example-driven approach, VPNs Illustrated explores how tunnels and VPNs function by observing their behavior on the wire. By learning to read and interpret various network traces, such as those produced by tcpdump, readers will be able to better understand and troubleshoot VPN and network behavior.Specific topics covered include: *Block and stream symmetric ciphers, such as AES and RC4; and asymmetric ciphers, such as RSA and EIGamal *Message authentication codes, including HMACs *Tunneling technologies based on gtunnel *SSL protocol for building network-to-network VPNs *SSH protocols as drop-in replacements for telnet, ftp, and the BSD r-commands *Lightweight VPNs, including VTun, CIPE, tinc, and OpenVPN *IPsec, including its Authentication Header (AH) protocol, Encapsulating Security Payload (ESP), and IKE (the key management protocol) Packed with details, the text can be used as a handbook describing the functions of the protocols and the message formats that they use. Source code is available for download, and an appendix covers publicly available software that can be used to build tunnels and analyze traffic flow. VPNs Illustrated gives you the knowledge of tunneling and VPN technology you need to understand existing VPN implementations and successfully create your own.

VPNs Illustrated is a great book for those wishing to understand network traffic at the packet level. Author Jon C. Snader was inspired by the earlier TCP/IP Illustrated volumes, and tries to reproduce the Tcpdump-style material found in Stevens’ classics. The level of detail found in VPNs Illustrated easily outweighs any problems this book might suffer, so I recommend you read it for in-depth knowledge of VPN traffic.

The book is divided into three parts. Of these, I found Part I ("Background") to be of questionable value. The introduction (ch 1) should not have been a chapter, and ch 2 ("TCP/IP Overview") should be replaced by a reference to existing volumes on TCP/IP. The crypto overview (ch 3) could also be replaced by a reference to other books, although as a non-crypto guy I found it a helpful refresher. The last chapter in part 1 finally gets to more subject-specific information, covering PPP, IP-in-IP, PPPoE, GRE, PPTP, L2TP, and MPLS tunnels. I really liked reading the author’s criticisms of certain protocols like PPTP and L2TP. He should have included Tcpdump traces of MPLS, since the other protocols featured packet data.

Part II included chapters on VPNs (ch 5), SSL (ch 6), SSH (ch 7), and "lightweight" VPNs (ch like VTun, CIPE, Tinc, and OpenVPN. Some of this material is very deep and probably unnecessary for most readers. The author explains messages exchanged by almost all of these protocols, which is information I’ve not seen elsewhere. Some may consider these descriptions obscure, while others (probably researchers and developers) will appreciate the analysis.

Part III covers IPSec. Ch 9 ("IPSec") should be part of ch 10 ("IPSec Architecture"). The remaining sections thoroughly address IPSec (11: AH; 12: ESP; 13: IKE; 14: the future of IPSec). I think chapters 10-13 are the best IPSec material I’ve read. They made more sense than others I’ve seen, although the complexity of IKE made ch 14 difficult to follow.

Throughout VPNs Illustrated, the author is not shy about sharing criticisms of various protocols. This is extremely valuable. He also repeats sound advice on practices to avoid (like static preshared keys) or measures to consider (defeating replay attacks). Because he illustrates so many protocols, he compares and contrasts them to emphasize key points. He also frequently cites authoritative sources like Schneier and Ferguson.

To achieve a fifth star in a second edition, I would like to see the author incorporate my previous suggestions. I would love to see configuration files for all of his examples in the appendices. He can move existing examples out of the main text to improve readability. Every protocol should have a corresponding network trace analysis, and the traces should be posted on a Web site. I would also like to see a summary of his thoughts on what makes a great VPN protocol, and then his ratings for various implementations.

You won’t necessarily be able to implement the VPN software discussed in VPNs Illustrated by simply reading the text. You will gain a great understanding of how they work, or sometimes, don’t work!

Review date : 2005-12-02
I bought this book aiming to gain indepth understanding of VPN technology, but I was disappointed. The key chapter 4, for example, try to explain tunnel concept left and right, but it mixed the general encapsulation and tunnel, and the verbose wording didn’t make it any clear. Using tcpdump trace to explain some of the field is both a blessing and curse, depending on how you look at it - I think the book is sort of strong in specific details but weak in overall conceptual pictures - however most of those details have been better documented in the RFCs.

Another example - when talking about generic tunnel skeleton using FreeBSD as example (ch 4.8), where some code snippets are presented, I feel some background and detailed illustration of flow/drawing is necessary to clear up the concept and why it correlates prevoius sections, but none given.

It may sound a bit harsh: though the author try to emulate Rich Steven’s style and dedicate the book to him, but it is hard for me to say the end product can really live up to Steven’s standard.

Review date : 2005-11-23
NOTE: This book is not for everyone, if you have not invested at least 40 hours looking at network traffic, I would recommend you pass.

This book is zero fluff, it makes you want to spin up your scratch boxes and follow along. In fact I did just that, I have to switch to a new ISP that requires PPoE and I was always curious how that worked, the book gave me just enough of a clue to interpret what was passing in and out of my house.

The world has a new grandmaster of tcpdump and I have seem some pretty good ones over the years. Once I designed a T-shirt for a SANS conference with the hexadecimal output from a tcpdump; only we flipped it so it was running down the shirt and rendered in green, to resemble the matrix.

The packet was a DNS reply. In the additional records we said good things about SANS; after all, gotta market to eat. There was an error intentionally placed into the shirt and we designated a prize for the first attendee to find the error. A student walked by wearing the shirt and the "4500" in the hex field caught one of the instructor’s eye. She followed him around murmuring, it is sideways, UDP, DNS, a reply, there are additional records, wait a minute that pointer entry is wrong. We watched in amazement, when she was done and looked up, the entire SANS faculty bowed to her. Because a mal-formatted packet can kill a packet analyzer the world needs people like Judy and Jon.

This is not a beginner book and Jon expects you to catch the 4500 stuff pretty fast. However, if you have followed the discipline of tcpdump instead of some packet analysis tool that spells out everything this book can take you to the next level.

VPNs Illustrated is rich in diagrams, including packet headers and state diagrams, examples of network traffic, and cartoons that explain the architecture of the system, or network. It is amazingly well edited, my only nit is on page 93, line 1 spacing off by one character.

The book has a strong linux bias, if you are a Windows person, you will be able to follow along for about 60% of the book using Windump, but you will not be able to use the tools or source.

This is the perfect reference for the person that knows networking and wants to really invest in taking it to the next level.

Finally, the dedication to Rich Stevens was over the top and heartfelt appreciated. I will never forget the man who taught me how to read a packet.

Review date : 2005-11-16
Given the complexity of VPN I was hoping to find a book that could explain key technologies in a concise and an organized manner. "VPNs Illustrated" does contain a wealth of technical information, but it failed on both counts.

The book offers unnecessary detail when trying to explain key concepts. It is so disjointed that the author is reduced to constantly referring the reader to other chapters to find information that is needed to understand a specific topic area. For example, the critical topic of IPSec is first introduced during a discussion of L2TP.

The book contains factual errors such as a typo describing "OC4" when the author meant to say OC48.

Overall, I was very disappointed with this text. It needs to be proofread and completely reorganized.

Power inverters convert low voltage DC (direct current) battery power to high voltage AC (alternating current) household power. These electronic devices are ideal for running household appliances and electrical equipment in your car. Laptop power inverters allow you to take your laptop on anywhere with you.

A laptop power inverter makes any traveling easier. It helps you recharge your laptop while you drive. A laptop inverter can convert the 12 volt DC battery power from a vehicle or airplane into 115 volt household AC electricity. Therefore, if your laptop battery runs down, you can simply plug directly into the AC outlet on the laptop inverter and keep functioning.

Since they are compact and lightweight, laptop inverters are easy to carry and store. A good product is equipped with a shutdown timer that protects your laptop from low voltage and high voltage damage, and over-temperature damage. Many varieties come with user changeable internal fuses. A laptop power inverter works best with a battery that is in good quality and fully charged.

Nearly all laptop inverters have built-in GFCI protection (ground fault protection), which is a characteristic that immediately turns off the inverter if it gets damp or wet. The device then readjusts the conditions and turns itself back on if the difficulties have been resolved. The GFCI protection avoids the consumer from electrical shocks and the possible risk of a fire.

Laptop power inverters are highly expensive, since they are pure (or true) sine wave inverters. True sine wave inverters provide the most consistent, highest quality output power. Laptops are sensitive equipment; hence they require a true sine wave. Every modern AC appliance operates on a true sine wave inverter, whether it needs it or not. So laptop power inverters can also use to run tool battery chargers, professional audio/video equipment, certain medical devices, and variable speed tools.

There are many power inverters available for laptops. Choosing the perfect inverter is always a challenge. Always select one that is rated high enough for the laptop(s) you are using.

This is a fine low-price router. Setup isn’t complicated. I ordered this product as a Gateway for all my devices, because I kept losing internet through my Vonage (Linksys) router/phone adapter. My wife complained a lot and looked accusingly at me every time she lost the internet. I installed behind my Zoom Cable modem (which works great–I don’t recommend the Motorola Surfboard modems provided by Comcast, which habitually lost connections and had us swearing at Comcast for two years before I finally ditched their lousy hardware). The Vonage router is now connected to this router–behind its Firewall. A separate cable leads from this router to a Linksys router/wireless adapter which feeds all my computers. This system has worked flawlessly now for a week. Computers can communicate and see all the printers, which wasn’t working before the switch. No lost connections. I’m sure one could spend two or three times as much and get a fancier product, but I recommend this BEFSX41 router/firewall for a household on a budget. My only caveat is that the documentation is minimal, but that seems to be true for most all of these economy products these days. They’ve got to economize somewhere with all the cheapskates, like myself, who want the technology for $50 or less. Setup isn’t particularly difficult, however. Linksys has done a good job of minimizing complexity for a product aimed at the low-end home network market. The product I got (from Tiger Direct) doesn’t have all the lights shown on the BEFSX41 listing in Amazon, so Linksys seems to have multiple variants under the same product identifier. My wife has stopped complaining about lost internet connections–that’s success in my book.

I got this router when out company switched to VPN for remote desktop connections to increase security. This is one of the worst routers I have ever used, and I returned it to Amazon after about a week. The longest uptime I have ever seen was about 12 hours. Their support was horrible, and told me that they would not support the product at all if I upgraded the firmware from their website. I have since switched to netgear VPN routers, and those have been up for about 2 years now. I used to recommend Linksys, but now I tell people to stay away, or carefully check the model and version number, and compare them to the reviews.

Review date : 2008-06-28
2 1/2 months into using our new Linksys BEFSX41 router I went to connect to the Internet and the router was dead (this was last night…I’m using an 8 year old HP Gateway Router right now). I have included what lead to my reason why I only give the router 3 stars to save others from wasting their time with product support.

With 25 years of working with computer software and hardware, it didn’t take me long to surmise that the power adapter was no longer functioning-it wasn’t warm despite being plugged into a functioning surge suppressor overnight. I doubted it was the router that was the problem. My husband further tested the power adapter with a power meter and the adapter was indeed dead (we also checked another adapter that we knew was working to verify the power meter was functioning properly, it was).

I checked the Linksys web site to see about a warranty issue since it was past the 30 day Amazon warranty. I found that there was an option to replace a defective power adapter with no need to return the defective unit (that was a clue that there is obviously an "issue" with the power adapters if they have their own RMA Option). I figured "cool, this should be easy"…famous last words. I now needed to get an RMA# to have a new adapter sent…unfortunately, this meant calling the Linksys/Cisco "outsourced to god knows where" tech support (I have a better name…"waste of time NO-support".

I ended up having to call THREE times because the first person didn’t give me an RMA# before hanging up (although he did agree with me that it was most likely the power adapter). My second call I was put on hold for just shy of 15 minutes with dead air before I finally hung up. My third and final call stuck me with an unbelievable airhead. After starting to ask me questions about an "ethernet card" (NIC), which had NOTHING to do with the router, she proceeded to ask me the same questions over and over, even though I had already answered her ("when did you buy the router?"…March 19th, "where did you buy the router?"…Amazon.com…"how many lights are on the front of the router?"…None, there’s no power getting to it…"so the power light isn’t even on?"….No. (this went for three rounds!)

Even though I explained that there was no power getting to the router because the power adapter was not emitting power, she proceeded to have me "reset" the ROUTER using the reset button. HELLO? There’s no power getting to the router so resetting it won’t do any good. I went ahead and held the stinking button in for 30 seconds. Now she says "how many lights are on the front of the router?"…NONE! There’s no power getting to the router!… And do you know what her response was??? "Okay, your router is defective. You will need to return it"….I held my tongue. I didn’t say what I really wanted to say to this poor excuse for tech support.

I got the RMA# I needed, checked the box for "replace defective power supply" option on the Linksys RMA web site page and proceeded with my request to have a new power adapter sent.

So, the moral of my story…If you can help it, avoid the Linksys/Cisco "tech support", because in my opinion, it’s a complete waste of time and another fine example of useless foreign outsourcing…corporate America, BRING THE JOBS BACK TO THE U.S. for pete’s sake!

Constantly breaks down, have to reboot. I’ve owned this router for 3 months and have 3 months of on and off performance - keep away!

Review date : 2008-04-21
I purchased this router 4 years ago and set it up in my office. Plugged in fine, worked right away, i really didn’t use the VPN function so this review will not cover it.
I loved the option to block content by keyword or by website name, the communication speed was great, no problems at all until recently where it stopped assigning new DHCP addresses, and within a couple of hours i lost the ability to assign new static addresses. Mind you there were only 4 computers on the network. a Call to the tech support yielded no result since the router was out of warranty. Upgrading the firmware didn’t help, hardware reset didn’t help, Buying a new router solved the issue.

Honestly though i strongly believe that linksys’s quality has been going down lately. I own several linksys routers and they all have at least one annoying issue.

Wired

This is the grandfather of networking, the bread and butter combo, the standard. Setting up a wired network is not very difficult, can be done inexpensively, and doesn?t require much prior networking experience.

What you?ll need

For internet sharing, you will need a Cable/DSL router. This splits your internet connections to multiple devices. If you simply need to connect multiple computers for file sharing, chat services, or games within the home, you can use an Ethernet switch. Then, of course, you?ll need Cat5 wiring.

How to do it

There are very few processes less difficult than setting it up physically. Simply plug your computers? NICs (Network Interface Cards) into the router or switch. If you have a cable router, plug the router into your DSL/Cable source. You will need some basic Cat5, Cat5e, or Cat6 cabling. Now, when it comes to software, network creation can sometimes be a beastly task but that depends fully on your operating system and I just simply refuse to go there.

Cons

Everything?s got its drawbacks and wired networking is definitely a thing. Cat5 cables can be somewhat attractive, but they?re still cables that you?ll either need to run through your walls (which is a lengthy, messy, and potentially dangerous process) or they?ll be trip hazards. This is the principle reason that the next options exist, in my opinion.

Wireless

Wireless networking is becoming more and more commonplaces in homes that need to link together multiple PCs or share an internet connection, but that don?t want to run cable all over their home. 802.11g technology with transfers up to 54Mbps are becoming very affordable, too, making it a very practical option for many.

What you?ll need

For internet sharing and networking, you will need a wireless router. Then, for each computer you want to network with, you will need a wireless access point which can be in the form of a PCI card (for your desktop PC), a PCMCIA card (for a laptop), or even a USB dongle (for desktop or laptop).

How to do it

This is another remarkably simple process. See the steps above for a wired network, just remove the cables. Plug your incoming internet connection into the router, plug the WiFi (receiving) cards or dongles into the connected devices.

Cons

This isn?t as fast as wired speeds (Cat5 is 200Mbps, Cat5e is 400 Mbps, and Cat6 is 1000 Mbps vs. Wireless? 54 Mbps). There are also distance limitations based on interference from other 2.4 GHz band-using sources (such as cordless phones) as well as walls and other obstacles. It is still a viable option for most homes, though.

PowerLine HomePlug system

The HomePlug alliance began to give people an option for wiring their homes without needing expensive equipment or spending a lot of time wiring. It uses your existing power cabling to carry a network signal, meaning you basically already have networking installed in any room with a power outlet. Very, very cool stuff. Hands down.

What you?ll need

You will still need a router for your internet connection. Beyond that, you simply need a PowerLine wall unit for each room 1 for the router. You will need short runs of Ethernet cabling (Cat5) for each room.

How to do it

Connect your router to a PowerLine unit via Cat5. Then connect each computer or laptop from its Ethernet card to another PowerLine unit to any plug in the same home or office.

Cons

If speed is an issue, PowerLine?s not the way to go. The max speed is 14Mbps and tests show that that decreases with distance from the source. However, it still works for most common internet needs. Speed would only be a real issue if you needed to transfer large files between computers on a regular basis or stream video from one computer to another.

This book gave a solid grounding in what is available and a broad idea of how to use each of the options, such as IPSec with Openswan; PPTP with PopTop, using SSH PPP, and other more proprietary VPN methods.

Some of the info is a bit dated; For example, many Linux kernels these days come standard with support for IPSec and PPTP as modules. I definitely recommend after reading this book and deciding on a VPN strategy, that you find quality web sites with more up-to-date information about how to configure your selected VPN technology on your selected Linux distribution. I chose Debian/GNU Linux myself. With this book and some updated information added to that foundation, I feel like I have a good start.

Review date : 2005-02-08
If you need to know, really need to know VPN internals and how to make them work, Oleg Kolesnikov has written a masterpiece.

Review date : 2003-07-29
Building Linux VPNs is the first book I’ve bought in the last three years that has the right balance between theory and practice. The first two chapters let you know everything you need to know about VPNs and network topologies and ‘gotcha’s (where should the DNS server go? How should I route?)

They get all this out of the way quickly. Many books that are dedicated to VPNs only talk about this part of the equation, and do so for hundreds of pages. Oleg and Brian get it all down so you can digest it in a sitting and have everything you need to know.

The remaining chapters cover specific VPN protocols. I needed to support PPTP for the majority of my windows clients, and IPSec for my remote offices and more recent laptops that suppported it. I literally built these VPNs by reading and copying in text (yes, I could have got the code off the web page, but nothing is better than doing it yourself) as I went along. Not a single problem, it was smoother than smooth.

I can’t recommend this book enough. If you want a VPN on Linux (or other Unix for that matter) then this is the book for you.

I don’t know what is hapening with this people…
I buy this book based in that reviews (all 5 stars) and when I open the book I am totaly disapointed. About the book: The examples is not complete and the text is confused. I do not recomend.

I’ve been struggling with PPTP and FreeS/WAN for years now and the hardest task I now have to deal with is teaching others the intricate nature of VPN’s, tunneling, masq’ing connections and linking private LANs together. This book has been an excellent resource to intruct others on how to administer our tangle of connections and taught me a few nifty tricks in the process.
 

The predicted end to dropping DS3 bandwidth pricing is premature as the downward pricing trend continues. Service providers are up against stiffer competition and are desperate for new customers to fill their pipes and turn a profit. If you’re ready to negotiate for a rock bottom price, first consider a few of the reasons for the drop in price on DS3 bandwith. A little preperation will allow you to take best advantage of the situation.

DS3 bandwidth pricing had reduced as companies have gone out of business and the large number of telecommunications companies are fighting for a place in a smaller market. While many service providers did have room to lose margin, many have come dangerously close to the edge of selling circuits at a loss and many have gone beyond this point. It seems that in the race to the bottom many providers failed to learn the lesson that selling at a loss does not create a long lasting and healthy company no matter how many circuits or widgets you sell. Many companies selling at a loss have already been in bankruptcy and look like they will repeat this exercise as they did not learn from their first go around. So, solvency of the DS3 bandwidth provider should be a consideration when looking at great bargains.

Another consideration in bargain shopping for DS3 service is the fact that all DS3’s are not created equal. Many providers are convinced (and rightly so) that customers are focused on price and are not concerned with quality of service. Many providers are now oversubscribing DS3 service connections as though they were DSL connections. This means you may not get the bandwidth you thought you would get. Make sure when you look for that bargain price you also review the SLA (Service Level Agreement) and make sure the contract protects you and guarantees you will get the bandwidth to which they committed. Remember, when bargain hunting for DS3 service you’ll most likely get what you pay for.

So the general moral to the story is by all means do negotiate for the best price you can get. But….ensure that critical factors such as reliability, Service Level Agreement, QoS, and scalability are met in addition to price attractiveness. For this I receommend sticking with a Tier1 provider for best price AND piece of mind. It just makes business sense.

Downloadable Ring tones - The Latest Trend

What can you say about ring tones? NOTHING … except that cell phones capable of downloading ringtones are the newest ?must have? item today! One of the fastest growing features today is ringtones, especially downloadable ones! There are other downloadable items available on the Internet too like Java Games. Various wallpapers and screen savers are hot too but by far the most popular feature requested is downloadable ringtones.

The cell phone and their various ringtones have become status symbols. Ringtones show that you?re up to date and happening. You can even take a test that defines which ringtone best suits your personality. You can truly display your lifestyle and certainly your musical taste on your sleeve.

This article will describe briefly what ring tones are, what?s currently available and what the future holds. It will also suggest a caveat to consider prior to downloading the multitude of formats of available on the market. Prices are low and the sky?s the limit, so read on.

* A Caveat Before You Buy!

* A Brief Glimpse At Ancient History.

* Other Products Available On Ringtone Websites
* What Can You Say About Ringtones

Just What Are Downloadable Ringtones?

Ringtones are the sound that a regular or cell phone makes when it?s rings. Early ring tones were simple chimes and on later models, a combination of chimes. Limited numbers of ringtones were available and mostly consisted of different patterns of tones or chirps. An example of one of the most infamous ringtones was the ominous? ring ring?ring ring? that is reminiscent of Todd Beamer?s last telephone call on 9/11. You can hear that ringtone featured as an intro to Neil Young?s famous song ?Let?s Roll.?

Ringtone technology developed quickly and has progressed a lot since that song was recorded. Originally, you purchased a cell phone and had a choice of monophonic ring tones that produced a one note song. The number of songs was extremely limited and downloadable ring tones were simply an Engineering student?s good idea.

Because of lightning speed technology and numerous service providers, one of the latest and greatest features available today is downloadable ringtones. When you?re surfing the ?Net you?ll find plenty of sites offering tones by today?s hottest musicians; you can pick monophonic, polyphonic or true tone formats. More on that later.

A Caveat Before You Buy!

The first thing you need to know before you select, buy and download a suitable ring tone is if your cell phone is up to date enough to utilize this feature. Like everything else in technology, cell phones have evolved very quickly. As a result the cell phone that you purchased just a year ago may not have the ability to fully access the type of ring tone currently available. So make sure you check. Re-read your manual or call your service provider to find out. It?s possible that you can upgrade your phone for a reasonably low fee.

What?s Available?

Ringtones are divided into three formats.

1. Monophonic
2. Polyphonic
3. True Tone or Real Tone

To understand this type of technology, a person needs to have a physics/mathematics background and understand musical composition. Luckily, all that is needed to know is what types of ringtones are available and what they sound like. The following is a description of three types of ringtones, monophonic, polyphonic and true tone. Most websites offer samples of each and once you hear an example, you?ll know what type you?ll want to use on your cell phone.

1) Monophonic Ringtones
Some of the first cell phones came equipped with the capability of having a one tone ringer. ?Monophonic? is the simplest of ring tone technology that uses a midi format. This ?one note wonder? changed ringtones. Gone were the chirps and chimes; now you could play a song. A monophonic ringtone is single notes playing a song. You can recognize your favorite song but it sounds a little lame. Most monophonic tones are offered free of charge because of more full bodied tones now available, but if you?re trying to make a statement, however, read on.

2) Polyphonic Ringtones
Polyphonic ring tones also use midi technology but the tonal quality is richer and has more depth. This is because polyphonic ringtones can play up to 40 notes or more. A quick example is the sound produced when Windows XP? starts up. It reproduces the sound of an orchestra playing a note rather than one instrument playing the same note. Polyphonic with its richer tonal quality sounds better than monophonic but when compared to MP3 quality it sounds pretty weak. Midi format may be adequate for basic ringers and great for greeting cards but if it?s real sound that you want for your cell phone, keep reading.

3) Truetone And Mp3?s
The future of sound for ringtones seems to be hifi quality. The real tone or true tone ringtones that can be downloaded onto your cell phone are equivalent to an MP3 player quality and sounds a little like an iPod.

True tone technology will allow the user to hear recorded voices such as Austin Powers announcing ?You?re phone is ringing, baby, yeah?. This recording is so convincing that people will be looking for Mike Myers. Songs like Outkast?s ?Hey Ya? and the Starsky and Hutch theme song are downloadable as well. With a built in microphone you can record your own or someone else?s voice. True tone ringtones will even mimic a real old fashioned telephone ring. How?s that for retro?

A Brief Glimpse At Ancient History

In the almost ancient past, cell phones came with one ringer and no features at all. Wall paper was something that decorated your home and SMS was unheard of. Cell phones were big and cumbersome and used only by the elite or as marketing gurus put it, ?Early Adopters.? Very few people owned cell phones because of the size and expense.

Digital technology changed all. All of a sudden a lot of people were buying and using cell phones. This was confusing because every time a phone rang, everyone in the room started to rummage through their bags and pockets to answer it. A unique sound was the answer and that is how ring tones of every description came into being.

Ringtones ? Where Do We Go From Here?

Some technical websites declare that the cell phone of tomorrow will replace the MP3 player of today. This will be possible once a dual use battery is invented that can hold a sufficiently long enough charge. The power would last more than a few hours and be easily recharged. The ?techies? declare that memory capabilities must be enhanced so that the user can download and store hundreds of thousands of songs. This isn?t that far off, in fact an MP3 player being replaced by a cell phone is considered possible within 5 years according to most technical websites.
