Are These Pictures Of The iPhone 5s ?
Apple has finally just managed to catch up with the demand for the iPhone 5 and we are already seeing rumours regarding the next generation iPhone.
The images claim to be the iPhone 5s which is expected to be released in 2013 and if you have been following the last few iPhone launches you will know that Apple are most likely going to follow their pattern in not changing the design on the 5s, Apple did this on both the iPhone 3GS and 4S. Following that pattern it is no surprise nothing has changed from the outside. The only thing that has changed on the back plate is the place of 3 screws (shown below).
This could just be a prototype of the iPhone 5 or this could be the next generation iPhone. Some reports have already suggested that Apple has put the iPhone 5s in to trial production at their Foxconn factories
