Unlocking a cell phone is neither illegal nor in any direct voilation of laws. Apple can't stop anyone from unlocking a cell phone and to be honest, I don't think it really cares. Apple is playing this recent iPhone unlocking news perfectly. If it overreacted and stopped the hack, it could stymie its future revenue gains, but if it endorses such a maneuver, it effectively leaves AT&T out to dry. Isn't it ironic that AT&T lawyers went knocking on the doors of the hackers while Apple lawyers sipped tea at home?"
