So I keep reading these post asking can I use att next if I want to use Apple in store pick up? The answer is yes here's how: Select the phone and carrier on the site along with the store that has in store pick up. When it comes to the option of how you would like to upgrade( att next 12,att next 18, 2 yr, and partial subsidize price) click either 2 yr if your eligible but if your not 2 year eligible click partial it will be high in price. Here's how you swap it once you get to the store let the apple person that you need to swap your pre order to next. They will then bring the phone out cancel the order and re-do the order using att next. The phone never leaves your sight durning this. They were able to do that today with me with my plus 64gig until they had a system problems. But it did work just have to go back and sign everything this week. I typed this using my 6 plus so I am proof it works.
