Thanks - I wasn't sure how reliable something like that would be. Obviously this thing is a big customer issue or they wouldn't even be bothered to investigate so thoroughly and potentially make changes to their regulations.
It looks like they are really only concerned with the radio transmitter aspect so it would have been ideal if there was a way to easily detect it. I thought there must have been a reason why such a device wasn't already announced.
