The device offers a wider, 3.5-inch screen with touch controls that vastly improve upon the iPod's scroll wheel. To scroll through a list of artists, contacts or photos a user runs a finger down the screen. A faster flick will move further down the list than a slow one. The iPhone features an improved menu structure that makes it faster to find playlists, artists and albums.<br />

The screen is also improved, allowing the viewing of video and pictures in either portrait or landscape mode. Switching from one to the other requires a flip of the fingers.
