I bought a iphone 3g 8gb on july 12th. I really want to be on the safe side and get the 16gb one. I would like to exchange it for a 16gb. However is there a 10% Restocking fee for it?? If there is i probably wont do it. Also what is the policy 30 days?? Do i need the account holder on the AT&T service there?? Also any thoughts on this as i am confused on what to do if i should exchange it or not. The reason why i want the 16gb is not because of music because i do not have more that half a gig of music. I am more worried about future apps and filling my iPhone up with it. Any thought or suggestions would help thanks in advance
