If you are digg addicted, David Cann have written a Digg interface for iPhone. The application available for download is written in PHP and using YUI and the Digg API. Usage is pretty simple, Use your mouse to drag the lists up and down, then try to flick them like you’re supposed to on the iPhone. The back button on the phone is also enabled.
