My wifi order on the 29th was showing shipping soon all day yesterday (first checked around 8am eastern). I received the Shipped email this morning at 02:14 eastern. Shipped via UPS. UPS says "Billing Information Received" for 2nd day air, Shipped/Billed On: 08/25/2010.
My amazon order page shows that it shipped August 25, 2010 03:13:37 AM "Shipment has left seller facility and is in transit"
Nothing states where it is coming from, but at least they all state delivery for the 27th.
EDIT: Also got the Amazon Payments email at 05:05 eastern stating activity for Aug 25.
