Just placed the order for a black one, but what if I were to change my mind in say a couple of minutes or days, is there a way to exchange it for a white one?
I would assume so...however you never know what a carrier would do if you bought it from them. Through Apple probably true, but they don't do ANYTHING other than sell iPhones on launch day at Apple Stores. I've tried to look at other things during a launch day and was told that I'd have to come back the next day.
