Okay this is a question on behalf of my friend. I am not an iphone user or ATT customer (F-Verizon.), so I'm trying to figure out if there's a way she can swap her 16GB 3G-S that she ordered online for a 32GB model (and pay the price difference of course). Her initial belief was the 16GB was enough space for all her music, but after some reconsideration she realized she wants the extra space. She already ordered the 16GB a week ago, but it still hasn't shipped. Is there any way she can exchange it? or do it at an apple store later if it is unopened? New to this so sorry if there's an obvious answer. Thanks in advance for any help.
