Hey guys just got a question for you. I purchased the 8gb iphone from o2. However, I did not sign upto the contract. I unlocked the phone using jailbreak, then one of my friends somehow accidentally relocked the phone using itunes. Once the phone has been unlocked using jailbreak is it possible that you could sign upto the contract by relocking the phone using itunes? I dont want to sign upto the contract I just want to make sure as I am afraid that he may have locked the phone and signed me upto the contract.
