Justin Long, the actor probably best known for his role in the "I'm a Mac" Apple commercials, has broekn the rules that his former employer set out. It appears that he has a jailbroken iPhone.

While on the Jimmy Kimmel Live show, Long took out his iPhone and started talking through an SMS exchange on his phone. The display from his iPhone was on a large screen so everyone could see the text. Then at one point you could see the Cydia app on his iPhone. Oops.

Check out the video for the proof.
