I think those ship from US will use Fedex and the one ship directly from Foxconn factory will be UPS.

I'm considering picking it up from the FedEx or UPS location, which would be just like going to an Apple Store to buy one. I ordered 2 hours after the keynote and I still don't have my shipping/tracking info though...
Has anyone called Apple and asked them to hold the package at the FedEx/UPS location without attempting delivery?
I don't think you're about to pick them up on the 16th, because delivery truck leave the warehouse at like 4-5 a.m.
