Cell phones and smartphones are part of the leading edge of technologies that change on a rapid basis. What was new and advanced one year is quickly left in the dust as brand new features and advances grab the attention of the public.
However, not everyone can afford to keep up with the latest trends and many people want a good, reliable cell phone that works for their needs. So, it's little wonder that there is a vast market for used phones that millions of people are purchasing at a fraction of the cost compared to new ones.
There are a number of reasons why you'll find so many people purchasing used devices beyond the fact that they cost less than new ones.
Relevance: Although it may seem that the technology is outdated, the truth is that they can remain operational and relevant for several years assuming that their programming is updated accordingly. Just like computers and laptops can remain relevant with new operating systems so too can cell phones.
Durability: Thanks to the materials used in constructing the outside casing as well as the improved electronics inside, these will last for several years of normal use. This means that used phones can be upgraded and stay functional at a fraction of the cost compared to purchasing a new phone every year.
Carriers: In addition to the traditional carriers, there are a number of new companies that offer low priced services that work well with used devices owners. Companies like ACN, Flash Wireless and FreedomPop offer excellent services for a low price that has attracted many users. FreedomPop for example offers free mobile phone and high speed internet service that has attracted quite a few customers.
As part of the trend with used cell phones, there have been companies that specialize in purchasing and restoring older devices so that they are compatible with new technology. They may not have the speed and all the features, but they are generally quite good and most people may not even notice the difference. This certainly bodes well for the increasing trend of older cell phones as they take up more of the marketplace.
The used cell industry is rapidly growing and is expected to expand at a very high rate in the coming years. This is due to the increase costs and life expectancy of these devices. Many carriers are now providing options for customers to bring their own devices and pay a lower monthly rate which is increasing the market for used devices.

Sony Ericsson W880i
Sony Ericsson W880i: the Walkman gets slim and sexy
Walkman phones have been successful in creating a reputation for being a nice bundle of features. But in order to put in as many features as possible, manufacturers have somehow overlooked the 'fat' size of the phones. With the rise in popularity of fashion solution and the growing clout for slim phones, it was, but obvious for Sony Ericsson to come up with a 'slim' Walkman phone.
The Sony Ericsson W880i is till date, the slimmest phone from the giant. The drought of slim phones from Sony Ericsson ended in a high note as the Sony Ericsson W880i is not only the slimmest with 9.5 mm width but also one of the lightest 3G phone at just 71 gm. Most importantly, the Sony Ericsson W880i is successful in maintaining Sony Ericsson's reputation for giving its user a nice bundle of features.
Being a member of the Walkman family, the Sony Ericsson W880i is a master technician when it comes to music. Endowed with an advanced Walkman media player V2.0, the Sony Ericsson W880i plays all popular media formats with great power and clarity. The phone has everything you'd expect in a music phones – A2DP Bluetooth profile for wireless stereo headset, 3.5 mm audio jack adapter, graphic equalizer, playlist support, memory card support and a host of treadmark Walkman features like Track ID, Mega Bass and Album Art.
3G technology of the Sony Ericsson W880i makes it a strong communication tool. The phone can take part in video calls and has a dedicated VGA resolution camera just for that purpose. The primary camera module is 2.0 megapixel with video capabilities. The triband phone is operational in five continents across the globe. The handset includes the easier to use NetFront browser so that finding and downloading your preferred web content is easy and quick.

What Is A VoIP Phone
In spite of the growing popularity of IP telephony, there are still many people who do not know what a VoIP phone is. What is the difference between a VoIP phone and an ordinary phone?
As far as you are concerned, probably not a lot. You can still use your own land-line phone if need be, though in it's simplest form there is no VoIP phone handset as such. Just a microphone and speakers will do. All you need is some software which is supplied by the provider.
You can use your normal land-line phone. Just like digital TV requires a box, either set-top or included in the set, VoIP needs a box which you can either buy yourself, or get from your VoIP provider. Once you connect your phone to the box and the box to your internet connection, you have your VoIP phone system using your own phone. Due to the connection speeds involved you have to have broadband or another high-speed internet connection.
Your telephone conversation passes through the internet in packets in the same way as any other file does. As you speak, your analogue voice signals digitized by the VoIP software into binary form, and the digital stream broken up into small packets which are sent through the internet. These packets each take their own fastest route through the internet, from computer to computer, till they reach their destination. This is the way that all files are sent through IP.
The problem with a streamed signal, such as a VoIP phone conversation, and a packet system, is that the packets do not always arrive in the correct order. This is due to the relative amount of internet traffic each packet comes up against, and the fact that they can each take different routes. Also, some packets are lost, or 'dropped'.
Modern software is becoming increasingly better at arranging packets in the correct order (often through slight time delays which allow them to be rearranged) and covering up 'dropped' packets. VoIP phone conversations are therefore more audible now than they were in the early days of VoIP phone systems.
As I said, you can use your computer microphone and speakers to make and receive conversations, but you can also get a dedicated VoIP phone if you prefer. It's all a matter of choice and does not significantly affect the services you can have.
Some of the services supplied free with VoIP phone systems are:
* Caller ID
* Call waiting
* Call forwarding
* Voice mail
* Conference calls
* Call transfer
* Group pick-up
Once you have your box, any calls you make to another VoIP are free–anywhere. For calls to non-VoIP phones there is a charge, but this is generally lower than normal land-line charges.
Your phone number relates to the adapter, so you can take this with you and use it on any computer with fast internet connection. You can also buy a VoIP phone to go with your laptop and make telephone calls anywhere at any time; just as you can with a mobile, but at a fraction of the cost, and usually free to any other IP phone. This is an excellent inexpensive solution for businesses with a network of offices – all calls between them will be free throughout the world.
Another cool feature is virtual phone numbers. You can get local area numbers allocated to your regular phone number, so that if your family live in LA and you are in New York they can ring your LA local number with their land line and speak to you in New York at local rates.
A VoIP phone is now an attractive option for anyone, both as a cheap alternative to a mobile phone and as a complete replacement for a land-line.

VoIP Again
Quick response from technical support that illustrates why I'd never suggest that my parents get an internet phone service:
"Some fax machines use the T.38 codec standard, to communication between themselves, the Lingo device does not support this standard. A common symptom of T.38 fax relay problems is a voice call that is established where a fax tone is heard, but the fax negotiation is not completed and the call is eventually dropped. Often this issue is associated with the VoIP - H.323 T.38 Fax Relay Issues. (H.323 is now considered to be the standard for interoperability in audio, video and data transmissions as well as Internet phone and voice-over-IP (VoIP) because it addresses call control and management for both point-to-point and multi-point conferences as well as gateway administration of media traffic, bandwidth and user participation.)"
I'm not taking issue with the response, just pointing out that this is not quite consumer-ready.

VoIP Update
A bit of weirdness with the voice over IP line today - I cannot send a fax over it. The fax machine works on the land line, and phone handsets work on the VoIP line, but no fax sending.
The provider's service has been good & I imagine they'll sort this out for me, but VoIP is, it seems, not quite ready for prime time. I have enough technical aptitude to sort through this stuff, but I can't imagine the generic non tech user putting up with it.

Internet Phone Update
Calling Cards
Some time ago I signed up for internet phone service - where your voice gets turned into data that goes out over the internet and then back into the phone network, rather than going via those old fashioned wires. After a few setup hiccups it seems to working nicely and I'm expecting to cut my SBC service back to a bare minimum (for net $$ savings).
Prepaid Phone Cards
I noticed this article in the Washington Post about the plans of Vonage, a VoIP provider (not mine) to offer services via WiFi - basically, you'd have a special handset that works at WiFi hot spots to let you make calls using that internet connection (i.e. not using up your mobile minutes).
It's an interesting idea but I'm kind of skeptical about this particular implementation of it. It means that you have an additional handset to carry, since it doesn't replace your mobile phone. And mobile service is so cheap that frankly it's hard to see that it will be worth it - especially since you will have to pay Vonage for the service. I can see it be useful if you have a WiFi network at your home/office - it could become your "land line" and you could tote it along when you are going to be near a WiFi hotspot so you can make or receive calls on your "land" phone number.
International Phone Cards
But it seems like a clunkier version of what I've got set up; I use my wireless number as my main number, and for $3 per month I have a service from Cingular that forwards all my wireless calls to my home number when I'm in the house (without using up mobile minutes) - I just pop it into a cradle and it's done.
