In a previous article, "Andrew Sarangan" said:
If the cellphone is able to transmit its GPS co-ordinates, surely it
should also be able to give that same information to the user.

Some of them can. A friend has a cell phone that one of the better hidden
menu items is to make the GPS data private - if you don't select it, the
cell phone company terms of service allows them the option to spam you
with text messages advertising businesses local to where you are.

There is also a program somebody wrote using the Google Maps API where you
and a community of friends can always see where the other members of your
community are at any time based on the GPS coordinates of their cell
phones.
