A recent find from 9to5Mac showed that iOS 6 shows 5 rows of homescreen icons when forced to run on a 640 by 1136 resolution. This resolution, is rumored to be of the upcoming iPhone 5 with the 4 inch display. So, obviously, you’d want to know what your favorite apps would look like in this resolution.

If you’re an iOS developer and are currently running any of the iOS 6 betas, you could probably do that with this little hack. All you need in order to do this; is a developers account and access to Xcode 4.4.1 along with iPhone 5.1 Simulator. Cedric Luthi has found a way to change the size of the iOS simulator to make it run on a 640 x 1136 resolution.

1.Download File.txt into ~/Library/Application Support/iPhone Simulator(don’t change the name of File.txt)

2.Edit/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app/Contents/Resources/Devices/iPhone (Retina).deviceinfo/Info.plist and add the following keys:
eagle
640
giraffe
1136

3.Quit the iOS Simulator app

That’s it! You’ll now be able to test and see what apps would look like on the rumored iPhone 5 resolution and probably design apps for this resolution. There are high chances that Apple could actually use this resolution. Make sure you’re a developer before trying this and good luck!
