My iphone application can run on devices with iOS 4 & greater + multithreading & camera is optional (since I can use photo library). I am using GCD for multithreading. Which keys should I mention in UIRequiredDeviceCapabilities so that my app will run on only iphone 4, 4S , ipod touch 4g & all ipad ?
If I set front-facing-camera then 1st gen ipad are omitted.
Any help is highly appreciated. Thanks
EDIT 1
I want to run my application on iphone 3GS,4,4S ,ipod touch 4g & all ipad.

All the details are available about the keys and their availability in iOS. Depending on the lowest iOS version you can pick up keys, those will be automatically supported by their latest version.
