I am getting an app developed for Iphone I need the user experience optimized for 4 inch screens but also support 3.5 inch screens. Is it better to have the app elements designed (in photoshop psds) for 3.5" or 4"?
I understand that with Xcode we can adapt the 3.5 inch design for 4" but will that affect experience for 4 inch screens? I really want an awesome user experience on the 4" screen.
