Hey guys i tried searching the forum for this but couldn't find anything and sorry if there is another thread about this already.... But i was just wondering has anyone here taken in a 16gb iphone 3gs to a genius bar and walked out with a 32gb 3gs i was wondering if apple does it obviously if they do it would be for a fee but i was considering getting a 32 3gs soon from ebay or craigslist but figured i'd see if apple trades models for a fee
