The iPhone 5 is beginning to look a little long in the tooth against the rest of the best phones around, so it's no wonder we're hearing a lot of information about a successor. In keeping with Apple's naming convention we've no doubt this will predictably, and rather boringly, be called the iPhone 5S.

The early arrival of the iPad 4 and the iPad mini - just eight months after the release of the iPad 3 in March - has meant that Apple still has the ability to surprise so the mooted release date for the next iPhone is still up for debate.

But it's now almost certain that the iPhone 5S will be accompanied by the cheaper and more fancy-free iPhone 5C (note the use of the word 'cheaper' and not 'cheap'... this is Apple we're talking about here, after all).

Nevertheless it's most likely that the iPhone 5S will hit stores in the latter part of 2013, following the trend set by the iPhone 5 and 4S. It's even possible that Apple will skip the iPhone 5S and hop right on to the iPhone 6, though there is little suggestion that this would be the case.
