these process of override does not work now.. and only changing the UI supported interface oriatations for ipad in info.plist will only temporarily solve the problem but will create problem when you will go for app validation and app sumbmission to app store..

you have to modify the keys like this..
UISupportedInterfaceOrientations~ipad
UIInterfaceOrientationPortrait
UIInterfaceOrientationPortraitUpsideDown
UIRequiresFullScreen
I have tested this...
