My latest update:
Regular non-Plus Space Grey iPhone 6, 64GB. Ordered from AT&T ~9:10AM.
This morning my status at the Business site was
Preorder Processing Expected Ship Date 10/13/2014-10/31/2014
In the afternoon, it changed to
Preorder Processing Expected Ship Date Pending Confirmation
and the regular AT&T site said BACKORDERED.
Now, in late evening, the Business site has switched back to
Preorder Processing Expected Ship Date 10/13/2014-10/31/2014
and the regular AT&T site now says PREPARING TO SHIP.
Sorry this is just more redundant info, but I'm reporting the facts, for whatever they're worth. By the way, I ordered through AT&T Next, and the interest payment for the sale was deducted from my account yesterday.
