I ordered mine on March 12, shortly have the store opened. Got "Billing information received" and Tracking number on March 30th. It just changed tonight, but says:
Location Date Local Time DescriptionWhat's This? CN 04/02/2010 8:26 P.M. BILLING INFORMATION RECEIVED
However, I did call the Apple Store yesterday, they said if the Apple Store status says that it shipped and will be delivered, to not worry about the UPS site lack of status. They said I'd get it tomorrow, despite the very recent location "CN" status.
We'll see tomorrow...
