I have an iphone 4s that was purchased by a friend on craigslist...turns out the phone was reported stolen and theres no way for at&t to unlock because of this. we need the phone unlocked to work on a different carrier. is there any legit method out there to do this your self yet or is at&t the only option? I have seen claims on ebay of people selling 'unlock kits' that can supposedly unlock any phone, but i cant help but be a little skeptical. anyone have success with this?
