GPS Cellphone Tracking - Track Anyone Anytime Anywhere

Here's a graphic where you can find out if Phase II (phone location
vs. just cell tower location) is available where you live. It's got
the worst choice of colors I've ever seen, btw:

Nope, Phase II sets location accuracy standards that have to be met
as well as deployment percentages.

The carriers are still free under Phase II to use either triangulation
or GPS.

The handsets for Phase II triangulation require extra stuff (it is
kinda, sorta like DME to get the aviation tie-in) but not GPS chips.
