Hi guys I own an iphone 3g that i have gotten from germany as i have lived there for 3 years it is unlocked and i guess it can be used with at&t and other us carriers. i know live in the US and want to sell my iphone 3g 16gb at a gamestop for whatever amount of money they were offering it on. the phone is in perfect condition and everything but they looked at my Model number MB497DN and compared it to theirs and it was off by 4 characters and they rejected it do you think this is wrong? or is there a way to spoof the model number? or would you just recommend me selling it somewhere else like ebay and craigslist?
