  •  It's worse than you think. A location function (2+ / 0-)

    has been part of cell phone systems since the very beginning.
    Initially somewhat rudimentary, non-GPS (of course, since cell pre-dates modern GPS), based on triangulation and signal strength from known, fixed cell towers (the antennae usually have/had three faces/360degrees), a maintenance command could resolve a given cell phone location to within a few dozen meters.
    This ability has of course improved considerably as the systems evolved, and is independent of the separate GPS-based location functions that became part of modern cell phones by law a few years ago.
    You can turn off GPS locate in your phone options, except for a 911 call, so I'm not sure anymore if the phone GPS is really inhibited from the system or govt.

    While it doesn't provide an exact location, it still provides the general area that you were in.
