This suggests that it is as illegal to use this as it is to use any other wiretapping techniques. Anyway, I assume you need to have the bluetooth phone's number to track the right one. By using something like Vumber with your cell phone and NEVER texting or calling directly from the phone to ANYONE, that makes even this software harder to use--at least for a phone. (Someone will correct me if I'm wrong.) My PDA's bluetooth is disabled and my laptop doesn't have the capability and I refuse to add it OR use wireless service.
