It will be the same height as the iPhone 4, but wider to accommodate a screen that will be about ten percent bigger. Flip it over and the sides and back will be one chamfered piece of aluminum. In the center of the back will be a large black plastic insert for the logo and antennas. The volume controls will again be one button. The home button will still be circular. The speaker and mike will be a series of holes instead of openings with grills.
