The casing is also labeled with an internal model number of N94, which has been associated with the next-gen iPhone when the number first appeared in an iOS 4.3 SDK. The N94 was identified as supporting an A5 processor, which is the same that’s used in the iPad 2 and the same that’s believed to be in the iPhone 5.
However, the iPhone 5 has long been rumored to feature a larger screen with a more dramatic design overhaul, featuring an almost tear-drop profile and a more rounded backing, whereas the leaked photo clearly shows a device with little change from the iPhone 4.
Rumors persist that Apple may be introducing a cheaper variant of the current iPhone 4 in addition to the iPhone 5 and that it may be geared for T-Mobile. This so-called iPhone 4S could perhaps be what we’re seeing here. Although this prototype looks very much like the iPhone 4, it has a redesigned antenna, A5 processor, and it very likely has support for T-Mobile’s 3G service.
