I sold my iPhone about a month ago and the guy who bought it is now wanting me to unlock it for him by filling out a form on AT&T's website. I'm a little leery to do it, considering I sold the phone for use on AT&T and not unlocked (so the guy is definitely wanting to save a few bucks), and then there's the fact that he's based in Russia (but has a location to ship to in the US), and despite the phone being a "gift", everything he's ever bought are phones, so I can't help but think he's a little shady. If I do it, the form is asking me for a wireless # and name - obviously the phone isn't on my account anymore, so what am I supposed to put? the # and name of the line the phone was used on? Are there any security risks associated with this (will he somehow be able to see the info I submit?)? What would you all do?
