The often rumored 960x640 iPhone screen could be validated today through an up-close study of the LCD. Looked at through a microscope, Apple's panel appears to have far smaller pixels than the iPhone 3GS or even the crisp 854x480 screen of the Motorola Droid. At 3.5 inches diagonal, the display SuperiPhone sees for the next iPhone would have a 320 pixels-per-inch density where the Droid's larger screen would measure just 265.
