From insanelygreattees.com:

All you have to do is make a 30-second iPhone ad. Keep it in the style of the “I’m a Mac” ads. There are three rules – First, your commercial has to include the words “I’m an iPhone.” It has to be about 30-seconds long. And it’s gotta be funny.

The entries could be hilarious and I’d be surprised if Apple doesn’t do some iPhone ads like these themselves.
