I\'m making a universal app based on the Utility App template. I\'ve selected a universal app and the MainView.xib and MainView~iPad.xib work properly on both device types. >
in the end i found the solution. it is really very very simple.
The xib must be named ~ipad instead of ~iPad, and ~iphone instead of ~iPhone.
The bad thing is the if you name them ~iPad, everything works in the simulator but it does not work on the real device.
