A teen from New Jersey unlocked the iPhone, so it can be used with non-US phone networks. Nice move.
The hack takes "about two hours and involves some soldering and skill with software" though, the guy says. So, if you don't want to brick your phone, maybe it's not such a good idea after all.
Also, I wonder how long it takes until the companies in question sue the bejesus out of that kid. Or, if they are smart, they just hire him. We'll see.
