After making some tweaks to the iOS Simulator application, it’s been found that iOS 6 will scale correctly to the taller 640×1136 resolution of the rumored next generation iPhone, reports 9to5Mac.

We were able to run the simulator at the rumored next-generation iPhone display resolution of 640 x 1136. We did this running both the current public release of iOS 5.1 and the upcoming iOS 6.0 The iOS 5.1 simulator displayed the home screen with a stretched set of four rows of icons. On the other hand, iOS 6 displayed five complete rows – as our sources said Apple was testing for taller iPhone displays.

Notably, the simulator will not correctly display five rows of icons at any resolution other than 640×1136 which seems to add weight to the prediction.
