OK, we know Apple is not going to make a 4.5″-screen phone for sure, so it’s going to be a phone with 4″ screen. Some blogs are saying that the resolution will be 640×1136 only because the width of the screen is not going to be changed. Well, according to rumors, Apple is going to use a completely different screen (Sharp or Toshiba), so the resolution (ppi) doesn’t have to be the same to match iPhone 4/4S.I predict it’s going to be a 4″ screen with 720×1280 pixels. Why? Simply because this will match the iTunes 720p content pixel-to-pixel while having even more ppi than the predecessor. We’ll see.
