Stack dimension for mobile application

[paolo mazza]

As far as I know,  the resolution of the screen of


iPhone 4  is   960 x 640

iPhone3 - iPod Touch is 480 x 320

iPad is 1024 x 768


So, if I want to deploy my application for iphone and ipad, what's the size
of the stack (width and height)  that I am supposed to set in order to have
a  full screen application in the iPhone and in the iPad?


Thanks a lot
