I ordered the 10th. 3GS 16gb Black
ATT says backordered
ATT Premier says "processing soon"
ATT rep said my order will ship the 18th via FedEx
ATT rep on http://www.facebook.com/ATT: "All orders placed via business channels on or before June 12th will begin to arrive as early as the 19th. Orders placed after the 12th will arrive 7-14 days after the order was placed."
Are you able to pull your order on the ATT Wireless Normal Site? And if so, what does it say?
If you look at mine...on the first post, the order date changed.
