That would be the iPhone 5 with a 16:9 screen

We have a few weeks when rumors keep popping up and concepts of future iPhone, call it iPhone 5 or iPhone (the end of the sixth-generation iPhone), the latest rumors suggest it might have a screen with a ratio of 16: 9 instead of 3:2, so you could expand the size of the screen without the width of the return is uncomfortable. The display we see in the design would have 3.82 inches, but the developers point to screens 4 or 4.5 inches retaining the current ratio, and that increasing the ratio would only serve to make incompatible applications, and developers would have to a different design for iPhones and iPhones 3:2 ratio 16:9 ratio. Ideally, increasing the size of the screen to the right point where the resolution is 300 ppi, a little less than at present, but still retinal display, so all existing applications are compatible with all iPhones.
