My girlfriend says this guy has a few iPhone 4's that he is selling for $50...so she calls me to see if I want one...well of course the first thing I think of is these are more than likely stolen but I can't get that verified so if I were to buy one or more is there a chance that these could either be tracked as stolen or something crazy with the GPS...? I want an iPhone 4 but not if it's stolen and I'd rather not risk getting into trouble when I can just get one from AT&T for $200 but just wanted to hear some thoughts...
