Serial number assigned. Only a week 36 =). Still hasn't shipped though, so it must be stateside (granted they can get it here really fast even from China... it's just not likely).It ALSO means we will be getting early production models. These typically have the best quality control because they were made during production ramp up not when they were pumping out thousands by the minute.
These are also the ones that get delivered early by accident on occasion. The ones from China are all held at the same place until dispatch together.
That's how I found mine. The apple order status still says preparing for shipment.Check fedex or UPS "Track by reference" page. My order in Apple's website still says preparing for shipment, but I used my phone number in the reference page and got my tracking number.
