Three months hale not yet passed since Apple released the iPhone 5 and we are already beginning to see rumors about its successor, commonly referred to as the iPhone 5S. Judging from the photos that have leaked lately, and assuming that they are real, the new iPhone will be almost identical to the iPhone 5, at least based on the outside factor. At first glance, both devices seem to be the same size and shape and sport the same 4-inch display. The back panel is also very similar, with only the fine-print information at the bottom being replaced by Xs, which, as some suggest, may indicate a prototype.
Where the differences are, is on the inside. The most obvious change is the arrangement of the screws for attaching the logic board. Apart from this, there are a few minor differences in the structure of the phone.
Assuming that there is some truth in these rumors, it may mean that Apple is following the same path as with the other launches, so it is highly probable that the iPhone 5S will look like the iPhone 5 just as the 3GS looked like the iPhone 3G and the iPhone 4S looked like the iPhone 4.
