I think I made a big mistake. I have a 1st generation iphone that I recently sold. The purchaser ask me to update the phone to 2.0.1 but I updated to 2.0.2 Now he tells me he was going to unlock it and jailbreak the phone himself The phone was never unlocked nor jailbroken before. Is it possible to unlock or jail break the updated phone. Can I reverse what I did. Have I lost my sale? Please help!!
