So i hammered out an agreement with a fellow from India to sell him my 3GS. When I arrived at Wendy's where he wanted to meet, I was greeted with about 5 people wanting to check out the phone. They started asking questions like when the phone was made, if i had a receipt (i don't), etc... Then one of them started asking if I could give him my user name and password for my AT&T account because he needed to get some information from my account... He said in order to unlock the phone or something, he'd need to get the info straight from the website... I got kind of pissed off, since he made no mention of any of this before I drove 20 miles to meet him. So he agreed to buy it for asking price, then said he'd email me about the info he needs. So why do they want to see my account info so bad? I don't really think i'm obligated to do anything besides sell him the physical phone. Anything after that is not my problem. What could they possibly use my account for? Also, I did a full restore straight from the phone's general settings menu. This completely wipes all information from the phone, right? I'm pretty sure it does, but just want to make sure since they were asking me weird things. Thanks!
