Can't say I haven't wondered that myself. Given that there are no serial 
numbers visible on the phones, I suspect that one could use the MAC 
address as a serial number, since these are probably allocated 
sequentially. Only the last 6 digits should change. My first phone 
(bought as an evaluator) has last 6 digits of 002175. The second 
shipment has numbers in the range of 002935 and up. It would be 
interesting to know if the MAC's from the phones that work are 
significantly higher than these.
