Does anyone know the difference on the AT&T website between "Preparing to Ship" & "Pending Shipment"? My estimated date is the same (10/13-10/22) but the status changed to "Pending Shipment" earlier today. I called the 877 number & it says backordered, I called the 866 number & it says "order received". I placed my order at 3:02am (12:02 CA time) Friday morning. So frustrating not having any accurate info from AT&T.
