Point your iPhone to digg.com/iphone and you'd browse the digg with more features than regular browsing Digg site using iPhone's default browser, Safari.
Digg iPhone was coded in 48 hours, and Kevin Rose promised the programmer to buy him an iPhone if he could match the deadline, and he got it done.
This application is still in Beta and here is some features offered:
* Native iPhone-like story scrolling
* Mini permalink pages with top 5 comments
* Login and Digging
* Jump to any topic
More features to come including Top Stories (24 hours/7 days). Well next is Pownce on iPhone, right Kevin ?
