Talking about the iPhone 6 here (I wish they let people edit the subject - Mods: Can you please add 6 next to the iPhone in the subject?). When Apple went from 480X320 to 960X640 to 1136X640, they were very careful about maintaining resolution scaling in terms of multiples. But if they go with a larger 4.7" or 5.5" screen, what resolution can they go to without making life difficult for developers? Obviously twice the resolution of 1136X640 will probably be overkill. But if they maintain the same resolution as the iPhone 4, the ppi will probably go below their retina threshold of 300 ppi. That only leaves going with some odd resolution that developers of iOS apps never developed for before. So what do you think will be the resolution of a 4.7" or 5.5" iPhone 6?
