I tried to add an iPhone 5c on AT&T Next to my existing account as a test to prep for the iPhone 6 pre-order. I have two lines in two different area codes on my account. When I added to the cart, I received the following message:
I'm now on the line with AT&T to figure out if I would be able to pre-order online or not in the morning.
