[aprssig] How about a new TH-7D with this?

[Greg D.]

I think some of them use triangulation from the cell towers (perhaps with an 
assist of some sort in the phone), and that there's not actually a GPS 
receiver in the phone itself.

If I'm not mistaken, the GPS units in cell phones use "lightweight" GPS 
algorithms.  The math is faster, cheaper, and less accurate.  I'm not 
familiar with the details, but my understanding is that a cell phone GPS 
capability is pretty poor.
