Just sharing my 2 cents. Haven't read through all the questions/comments. So I did the iPhone 6 preorder last year through AT&T premier site. I remember getting my phone (4-5 days after launch) after ordering 4 minutes before midnight. I had a target date 4 weeks after launch and at one point it was like mid November. The day before I got my phone I received my tracking number and it was already on it's way. I would expect the same behavior for most of you folks in here.
Never again will I deal with AT&T premier. No one in AT&T customer support would ever directly answer me. Tweets/Phone Calls/Live Person web chat. This year I ordered through Apple's web app about 30 mins after preorders went live. And have had no issues with my order thus far. There was a billing error on apple's side, and I called in spoke with a manager and she took care of it, and even followed up with me the next day on her own time. Apple support is why we pay the premium price.
