A hacker from New Jersey has unlocked the iPhone, enabling the device made by Apple to be used by any carrier.

George Hotz unlocked the iPhone, and has connected it to the T-Mobile Network. T-Mobile is a major competitor of AT&T, who is the sole operator for iPhone.
Hota says to do the hack takes 2 hours, some knowledge of software and soldering. No word yet from either Apple or AT&T.

The hacker hopes that people will unlock their own phones  on their own, he doesnt want his discovery to be used to gain profit. His next project will be to unlock the phone without any soldering.

Hotz says it took 500 hours of work to discover this.
