Apple is preparing to release a new iPhone with a larger screen later this year, and while multiple reports have indicated that the screen will be larger, the exact dimensions of the screen and its resolution have so far been guesswork. Some industry watchers have speculated that Apple could stretch the iPhone software’s interface and retain the iPhone 5s’s screen resolution of 1136 x 640. This approach would allow all iOS software and App Store apps to function normally on the iPhone 6 without work from developers. The downside of this approach would be that the iPhone 6's display would fall below Steve Jobs’ somewhat arbitrary 300 pixels per inch definition of ‘Retina’ for a phone. Just like with the transition to the iPhone 4's Retina display in 2010 and the transition to the iPhone 5's taller screen in 2012, Apple is preparing major resolution changes for the iPhone 6.
