I have the 7 Plus and am on the AT&T Next plan that allows me to upgrade every 12 months. I'm just wondering whether I'll be able to preorder the iPhone 8 online (assuming pre-orders are available)? The Next program requires you to trade in your old phone so does that mean I will only be able to buy a new phone in person, or is there still a way to do it online? If I can do it online, will it work with both Apple and AT&T online sites? Any thoughts/information is greatly appreciated.
