I wonder if using Next has anything to do with it. My wife and I went to an AT&T store Saturday, the day after preorder day. We combined our accounts into a family plan and subscribed to Next, each of us ordering a new phone. She ordered a 6, 64gb gold and I got a 6 plus, 64gb space gray. They told her late sept, early Oct. and told me into November. I confirmed this on the order status page. Well, today I got the email that they shipped, both of them in the box. Not sure how and sorry for the people who were up at 3am ordering.
I subscribed to Next also in a store on Friday afternoon. Mine is still showing the 11/09-11/27 dates
