Due to size...yeah, I know, quit groaning and don't even start with the "didn't anyone tell you to buy the biggest...". I know. I should have, but at the time I was buying my cheapskate hubby was standing there saying that the 16 should be big enough and I caved. Anyway, so how hard is it to exchange your iphone for a bigger one? Do they make you pay the 10% restocking fee to exchange for size? Should I go back to the original store to do it? Or, can I go to the Apple store? Can I do the exchange at the Apple store, or do I have to return the current phone at AT&T where I got it? Does anyone know? Also, the apps that I've bought already- they are saved on my computer when I sync, right? If not, how do I make sure I don't lose them? Sorry If there's some newb questions, this is my first iPhone ever.
