I feel everyone's pain here... I started my ordering process at 2:00am central time on the 27th. Used the Apple store app on my iPad and kept getting "error" messages. Finally got my order through at 2:45am and my wife's order through at 2:55am. Both with AT&T next. We both have a delivery date of December 5th - 11th. There has been no change in my delivery date at all. I even called Apple with no luck. They said "we don't change delivery dates" "Your order will be there between Dec 5th and the 11th" I was like "thanks, Thanks for nothing, I can read!"
So if you're getting your phone before December just count yourself lucky and it could be worse. I haven't even seen anyone's delivery date as far out as mine. I could probably order today and get the same date.
FYI: Mine Space Gray 64gb. Wife's Silver 64gb.
