It may not sport a bigger screen or a different design, but the iPhone 4S is certainly a step on from its predecessor, although much of the attention will be focused on just how big that step is.

Sporting the already-lauded A5 processor, improved aerial signal and a better camera, the hardware changes to the iPhone 4S from the iPhone 4 are by no means striking. It's difficult not to feel a little underwhelmed that an incremental increase has been 16 months coming.
