There have been a number of reports regarding a bigger screen on the next iPhone, but this most recent one comes with the numbers, which makes it hard not to take note of. According to 9to5 Mac’s sources, Apple is currently testing a pair of prototypes – codenamed N41AP (5,1) and N42AP (5,2) – that rocks screens that stretch out to 3.999 inches diagonally with a resolution of 640 x 1136.
If true, the new iPhones should still feature the same screen width, but with a longer display that amounts to a 16:9 screen ratio that should be able to play full HD movies without being bordered by black bars.
The source also described new interface features on test builds of iOS 6 that are designed to take advantage of the new screen’s resolution, with tweaks that feature an additional row of icons for the home screen and app tray. Other physical details include the usual home button (apparently, it’s not up for extinction just yet) and a smaller dock connector.
