The size of the iPhone 5 screen has been indirectly presented in iOS 6. More precisely, this is a screen resolution of 640 x 1136 pixels supported by iOS 6 which seems to indicate the size of the screen.
The next generation iPhone should be unveiled next month. Rumours have been circulating about this device, with various rumours startingwith Asian suppliers, with the news then spreading across the web.
But this time, it is the development kit for iOS which has provided indications about the iPhone 5. This integrates a simulation tool aimed at Apple’s mobile OS.
While iOS 5.1 has been specified in this simulator, the increased screen resolution means that there will be more space between applications with iOS 6. To do this, you have to enter a resolution of 640 by 1136 pixels into the simulator. From here, 5 application rungs appear on the simulator instead of the normal 5 that appear on the current iPhone (see photo below).
This could therefore be the resolution of the future iPhone. A small calculation (thanks Pythagoras) indicates that if the iPhone 5 keeps the same pixel density of 326 ppp as the iPhone 4 and 4S, its screen would be 4 inches: (640^2+1136^2)^0.5/326=4 .
This therefore corresponds to the insistent rumours that this would be the screen size of the future iPhone.
