jeez. i ordered on the 20th as well from at&t.com and still have "in progress".
congrats on getting yours shipped though!
I ordered the 22nd, so I've obviously got some time to wait. But I spoke to a very helpful and understanding rep today. She said that it wasn't listed "backordered" because it wasn't really backordered - that they had phones and that they were begin shipped out from centers as soon as they arrived. So the actual shipment center might have none on hand, but that shipments to those centers were in progress... who knows exacly what that means.
