A leaked photo shows an alleged motherboard for an "iPhone 5S," according to iOSDoc. The board is said to be roughly similar to the one for the iPhone 5, which may support views that the device will be just a modest upgrade, for instance keeping roughly the same dimensions as its predecessor. The photo does show an A7 processor, however, which the source claims is a quad-core 1.2GHz chip, paired with PowerVR's quad-core SGX554MP4 graphics.
