HiRez - Thank you for a very interesting, thought provoking reply and the links.
All along, I thought there was adequate encryption or authentification safeguards with BT...obviously that is not entirely correct. So, for the time being, it sounds like the only foolproof protection is to remain 'hidden' mode. I wonder how many people with BT just leave their phones on 'discoverable' mode? Dunno, but still have to [want to] believe the odds of getting "BlueBugged" are pretty slim.
I was a bit relieved to see Nokia, Sony-Ericsson, and TDK rather than Motorola phones slammed, as I was headed in that direction. When checking BTenabled cell phone features, I will now be looking very closely at the ease of 'toggling' between modes.
