iphone sdk - Itunes connect how to change device requirements?

What is it im supposed to set in the plist so that it shows that it does not work on the ipad on itunes?

its somthing to do with this http://developer.apple.com/iphone/library/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/AdvancedFeatures/AdvancedFeatures.html but I dont see anything that seems appropriate?

Im s开发者_如何学Pythontill kind of noobish so I'd appreciate a really simple answer or as simple as possible.

Thanks for your time
