Look, I've been reading this thread and see it's largely devoid of any actual hard info, so take this with an entire salt shaker...
I am Premier (ugh), ordered at 7:45am ET on 9/21, got only the one confirmation email, and have a pending debit on my charge card. I just got off the phone with a supervisor in the retention department, in my experience one of the most informed at AT&T customer service. He researched this order for a while, and it looks like Premier customers who ordered on 9/14 but who's status shows a 9/15 order date are in the 14-21 day order queue.
Even more frustrating, I asked him to cancel my order--to go to Apple Store or Radio Shack instead--and he was unable to even do that. I'm waiting for the rep to call me back before 6pm ET today with an update on the cancellation request, which of course impacts my upgrade eligibility and being able to get a subsidized phone in a bricks and mortar store.
I am in the exact same boat as you are. Same but I ordered 2 phones. Apparently AT&T is going to make me wait for my order, then return the phones back to them. This could be a month or longer. Not good.
