Apple's iPhone 4S could see mobile phone recycling surge, says SellMyOldMobilePhone.co.uk.

According to the mobile recycling comparison site, smartphones carry the biggest resale value of all handsets and as Brits clamour to get their hands on the latest iteration of Apple's popular smartphone, which was launched yesterday (October 4) at an event in California, they'll be quick to cash-in on the this value of their current handset.

"iPhone owners are like most technology buffs and will clamour for the new model as soon as it is available. The iPhone 4 and even the 3GS  will be relegated to the annals of history, but not before many owners have cashed in, in what could be the biggest spike in the growing phone recycling industry's short life," said Graham Miller, director SellMyOldMobilePhone.co.uk.

"There will be an upgrade frenzy, which will start with the Apple fanatics and continue as contracts come to an end over the coming months.

The highly-anticipated Apple iPhone 4S retains the same thin glass and stainless steel design of the iPhone 4, but benefits from a dual-core A5 chip which according to Apple delivers twice the processing power and up to seven times faster graphics than the previous iPhone.

The handset also benefits from a dual-antenna that will intelligently switch between two antennas to send and receive, and Siri, an intelligent assistant that helps you get things done just by asking. For example if you say will I need an umbrella this weekend, it understand you want a weather report. An 8Mp camera with a custom lens, grid lines on screen and ability to capture video in full 1080p HD, also feature on the device that will run iOS 5, the latest iteration of Apple's mobile platform.

iOS 5 benefits from 200 new features including iMessage that allows users to send messages, photos, videos and contact information to other users of the app for free over Wi-Fi and a new Photos app that ensures images can be cropped, rotate and enhanced on the device.

Currently Envirofone is offering £270 for a 16GB version of Apple's iPhone 4 while Mazuma will stump up £265 in exchange for the handset. If Brits are prepared to go without a handset for ten days (the iPhone 4S will be made available on October 14) , or are happy to use an old feature phone they've got stashed in a draw somewhere, they could find themselves with a healthy wad of cash to put towards the iPhone 4S.

Although it's worth noting the amount the iPhone 4 is worth will decrease quickly as the launch date approaches. UK pricing has not yet been released for the iPhone 4S but in the US the device is priced at $199 for the 16GB version, $299 for the 32GB model and £399 for the 64GB capacity device. This was the same price tag Apple gave the iPhone 4 in the US last year. In the UK, the device cost £499 for the 16GB model and £599 for the 32GB capacity version. This gives a good indication the iPhone 4S could cost £499 SIM-free direct from Apple.

"This is great news for this fledgling industry, but also for the environment and for the pockets of those who have a handset to sell on. However, there are still millions of people not getting on board with handset recycling, which means there is huge potential for growth in the industry, with the new iPhone helping it to be realised."
