As it turns out, Chinaman28 must have known that the model of the Nokia Lumia 920 in his possession should not have been sold in the first place as it had the letters "MSFT" laser etched into the back of the phone. That happens to be Microsoft's NASDAQ stock symbol. In addition, when booted up the phone, the words "Not for re-sale" popped up in red.
The bad news is that the version of Windows Phone Blue seen on the handset was only an early model and the notification center has since been removed from later versions of Windows Phone Blue. There is no word on whether the weekly calendar view or the ability to close down apps from the multitasking view have survived to the latest iteration of the OS.
