Yeah, I wouldn't want my answer to be interpreted as providing evidence for it. I'm not advocating breaking any laws in this forum, but especially not laws of physics. > As Eleanor said, if there is no power source attached to > telephone, or to whatever secondary tracking device installed in > the telephone, then it is not possible to track someone.

On a specific device, you could imagine a secondary battery powering the tracking device (er, the radio) but it's hard to imagine a scenario where that's the easiest way to track somebody. The conversation I had with the security researcher was actually about a related question, and that's whether "airplane mode" could be trusted as well. Again, I don't want my acknowledging a theoretical possibility to be taken as advocating a hoax or anything, but the agreement was that SOFTWARE solutions like airplane mode can't really be trusted, and some processor components do not have open-source software options. Of course, on a current iPhone, there isn't an option to remove the battery. Hope that clears things up a bit!
