Apple iPhone 4S

Faster processor ; Siri ; 64GB storage

Still expensive ; No iTunes in the Cloud (yet)

So, as previously mentioned, the iPhone 4S is the most powerful and feature-packed phone that Apple has ever made. The camera, processor and antenna are all well-needed improvements. And Siri is eccentric genius, if a little before its time. However,...

Great camera ; fast processor ; superb graphics ; slick OS ; quality screen ; Solid feel in the hand ; Siri voice recognition

Costly ; No flash integration ; Outdated contacts menu

As you can see, Apple has altered its antenna band technology to move the gaps that plagued the iPhone 4's reception to a less-touchable location. Next Page: Interface

Quality design, new iOS 5 features keep it competitive, PC-free living, new camera is excellent

There isn't a huge change from the previous version, battery needs careful management

It may not be the most thrilling upgrade ever, but Apple has put some thought into making the iPhone more useful, and has largely succeded in improving it hugely. Siri and the new camera are the two main improvements in the device, and both are useful...

Since iOS 5 is available for free, there’s not a huge reason for existing iPhone users to upgrade to the 4S. If, however you’re not sold on Android, then there are enough features here, including Siri, its sharp display and superb camera, for you to...

Great camera; surprisingly handy voice controls; no reception problems; clever new software features

Retains smashable glass front panel; screen no longer the biggest or best; 32GB and 64GB models are expensive

It may not look as amazing as the iPhone 4 did when launched, but this clever update keeps the iPhone up at the front of the smartphone pack

Still the slickest smartphone experience ; New camera features are great

Smaller screen than the competition ; Still no Flash support

It's hugely expensive, but well worth it if you can afford it. It's fast, has a great camera (and video capabilities). Siri isn't quite there yet, but in time, it should be an invaluable time saver

Faster processor ; Upgraded camera ; iOS 5 ; Voice assistant (Siri)

A larger screen would be welcome

Apple has its reasons, no doubt. Battery life remains an issue for 4G phones and Apple must have decided that, at this point, it couldn't offer its optimal customer experience on a 4G handset. Customer experience, after all, is really what Apple loves...

Meanwhile, for GSM customers, the iPhone 4S now supports HSPA+ 14.4, so the smartphone is capable of reaching theoretical data transfer speeds of 14.4Mbps down and 5.8Mbps up. It's certainly an improvement over the current model, but disappointing that...
