Earlier this week, we broke the news that Apple’s upcoming version of iOS 6 is fully scalable and aware of taller, larger iPhone displays. The display resolution of 1136 x 640, a resolution we first reported in May that Apple is testing for future iPhones, shows a seemingly perfectly tweaked version of iOS 6. As we revealed earlier, this means five rows of home screen icons and tweaked native app user-interfaces.
