Hi guys, new to the forum, please excuse me if I am posting in the wrong sub-forum. I need advice/help so this seemed like the appropriate place. Recently I re-upped my contract with ATT and ordered 2 iphone 3gs, one for myself one for my g/f. I bought them online from ATT, when I received them I activated mine but my g/f decided she didn't want to pay for the data plan. She said she could just use mine my phone if she wanted to surf. So instead of returning it I thought I could make some quick extra bucks by selling it on Craigslist. I was shocked to see how much they were selling for on Clist/Ebay. So I never activated it and removed my SIM card before I sold it. The guy I sold it to is now emailing me saying he was planning on unlocking it and is unable to do so because it is not activated and says he needs the SIM card that came with the phone to activate it. He does not have a contract or service with AT&T. So my question is how should I proceed. I don't want to be a jerk and not respond, but should I give him the SIM card? Doesn't the SIM card contain my account information? Can he unlock the phone or activate the phone without the original SIM card? Thanks, AJ.
