According to Pop Herald, the iPhone 5 will pack a 4-inch screen—up from the iPhone 4S’ 3.5-inch screen—forcing app developers to upgrade their products to prevent pixelation.

BGR also reports rubber or plastic bumpers around the screen to accommodate a new antenna system. Citing a close source, the blog confirmed a fall 2012 release, though anyone could make that call given the drop date of the 4S this year.
