Well, of course it does. Otherwise, it wouldn’t know to switch your signal from tower to tower as you move from place to place. We’re all aware of that, and most of us have seen crime dramas where the bad guy has been pinpointed as being at the scene of the crime at the time the crime was committed by examining the bad guy’s cell phone records.
What is surprising though, and something which you may not know, is that your cell phone provider keeps the records of where you were, and to whom you spoke, for a really long time, and the cell phone providers are not too eager to tell anyone what they actually do with all that information.
A German politician decided to find out. It took him quite a while, but he was finally able to get a copy of his records and discovered that his phone company recorded his lat and long coordinates 35,000 times in six months. Wow! Suddenly, it seems every one of us is like an antenna, beaming up our whereabouts continually. It’s a wonder there are any missing persons these days. Guess they drop their cell phones somewhere along the way.
