Bluetooth and phone security

Some Singaporean students have figured out how to use Bluetooth to turn off the cameras in Nokia’s phones, according to an article in Gizmodo, via a long chain to a now deleted newspaper article.
I wonder if they turn it back on when you leave the area?
However, Loosewire, the earliest still working link, implies that software is loaded onto the phone.
There have long been rumors that phones can be remotely, and silently activated, to act as bugging devices by law enforcement. Activating the camera remotely is pretty similar. It wouldn’t surprise me if BlueTooth Security vulnerabilities lead to either of these functions being controllable by whoever’s nearby. I wonder how much it would cost to repair every Nokia/Bluetooth/Camera phone in an area after someone with a high powered radio sent them all a message?
