iPhone 3GS, black, 16GB --> iPhone 4S, white, 32GB [AT&T]
I still love my 3GS...I've never had a single problem with it since I got it on launch day. But I really need more space...I can't even download updates to my apps from the phone right now because I don't have enough space left. I think the 3GS is going to go to my mom, if she wants it.
