Long story short. My brother lost his Iphone, so he called up o2 and got a replacement sent to him, and got the lost phone locked/blocked... whatever they do to lost phones. Well he now has a new iphone, and his friend just came round and dropped off his old phone, that he had found behind the sofa in his house. He offered the old locked phone to my girlfriend, as basically an ipod touch. We were wondering if we jailbreak it would it become usable as a phone again? Would it unlock it to any network?
