I placed the order on 9/14 and was not processed until 9/17.
I checked last night and it was off of backorder, but I still have not received a tracking # or anything.
Well - if yours was a Premier order too, and assuming there's some kind of logic behind this whole process, then I'd hazard a guess that your shipment will be 24 hours behind mine (i.e. you'll receive tracking tomorrow with delivery Friday).
That said, we cannot possibly make the aforementioned assumption with any kind of confidence. AT&T has successfully thrown logic completely out the window.
