My cell phone broadcasts when it is on, like all cell phones...but it does not broadcast my position..all anyone could know is what area of reception I am in, and that can be more than one.
Wrong. Your position can be caluculated to within a few feet. Mobile phone "GPS" does not use satellites, it uses signal strength to antennas and the location of the antennas to calculate where you are. You have been bagged and tagged.
