BRG claims that sources close to Apple are telling them that the next iPhone will be released in the fall of 2012, bringing in a completely new design with an all-aluminium back.
We have also learned that Apple is planning to use a rubber or plastic material — similar to the material used in the company’s bumper cases — that will be built into the new iPhone case. In all likelihood, this material will be used as a bezel surrounding the front edge of the phone (like the iPhone 3GS bezel) and it will serve two purposes. First, 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.
While BGR has had solid Apple information in the past, they've recently been far more miss than hit, especially where new iPhone models and releases have been concerned. However, it does make sense for Apple to stick to a new fall release cycle for the iPhone given the iPhone 4S release changeover earlier this year, and the need for a strong, fall, hero device now that iPod has declined.
