a friend of mine wants a new phone for christmas. I've had my old iphone 2g laying around for a while and let him try it and he loves it. He doesn't want to buy one from att because of how much the data plan is. The battery on it lasts about a day and a half and there are several scratches and dents on it. It was definitely heavily used. He's a friend, so im not trying to make money off him, but i know i could get alot off ebay for it. What's a fair price for a friend? I've seen used ones go for about 200 on ebay, but they're pretty good condition. what do you think?
