So, I know what everyone is going to say but I 'settled' this morning for the iphone 7 when I originally wanted the plus. I used my At&T next upgrade to get it. (14 day return policy). Question is.. is it possible when online Apple store reservation open to buy the iphone 7 plus if they have it even though I already used my Next upgrade? I would of course want to return the iphone 7 to the at&t store. I know I create this mess!
