You think this is funny! For 911 response purposes, the cell phone

able to receive calls.
Really?

(The newer phones have GPS receivers in them,
and the
cell sites interrogate the phones for location every couple of minutes.)
The cell
phone companies are required to keep this location tracking data for 7
years for
law enforcement purposes.
Cite, please?

Well, the phone co's have this data laying around, what can they do to
make money off it?
So, they sell it to data banking outfits, who figured out even the
triangulation data
is good enough to tell which store a consumer is visiting, and the GPS
data is
good enough to tell when you are in the cosmetics aisle, and when you
are in the
pet food one.
I call bullshiat. I've never seen a GPS unit that works indoors.

Then, they combine this with credit card info, and they
can figure
out what you bought, and when!
mmhmm ok. I'm afraid that I'd be astonishingly uninteresting to them
then.

See if it works...hang around the tampoon isle and see if you get some
cupons in the mail.
