BGR reported that the iPhone 5, slated to be released in the fall of 2012, would have a number of differences to the current 4/4S models. The back will be aluminum and it will likely be surrounded by a plastic or rubberized bezel according to the report.
It will join the glass iPhone face with a new aluminum back plate. It will also cover a redesigned antenna system that surrounds the device, allowing Apple to build the rear case out of aluminum without having to use a large plastic insert above the antennas as the company does on its iPad 2 Wi-Fi + 3G.
The last we had heard from our contacts at Foxconn was that the iPhone 5 would be delivered in the summer of 2012 along with a slightly bigger screen at the same resolution, faster processor and redesigned form factor.
