BGR has learned a number of details surrounding Apple’s next-generation iPhone from a close source. For starters, we can now confidently say that Apple’s next iPhone will launch in the fall next year, around the same time that this year’s iPhone 4S launched. 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. Earlier reports suggested that Apple’s next-generation iPhone will feature an aluminum case similar to the one found on the iPad 2, as well as a larger display around 4 inches.
