MacRumors has laid its hands on a couple of images purporting to show the inside and rear shell of the next iPhone.
The images seem to show the same logic board that appeared in a leak earlier this week. While the main chip isn't conventionally branded with an Apple A-series prefix, the date stamp suggests that the silicon was manufactured on the 43rd week of 2012. Rather older than expected, that suggests that this could be a very early prototype. Or, perhaps, fake. Difficult to tell.
