According to the OP, Grey contacted the bar several times asking about the phone - this is directly from the bar owner.PROVE IT!
Why, would an Apple Employee, TRUSTED to HAVE a PROTOTYPE in his possession, take it to a BAR that is FULL OF PEOPLE and CAN SEE a digital device, then ACCIDENTLY LEAVE that SECRET PROTOTYPE in a PUBLIC PLACE when he left and then NOT ATTEMPT to call, track or contact the device before it was wiped????
I'm waiting
My guess is that the decision to wipe the device was out of his hands - the phone contained classified info and wiping such data is SOP for companies the minute the companies knows that the device is lost or stolen. Besides, taking the device is pointless because find my phone is not functional in OS 4.0.
In other words, the fact the device was wiped matters not.
