I think you'll find GSM coverage in the U.S. outside of major metropolitan 
areas is sparse, especially west of the Mississippi River.   Your GSM phone 
isn't gonna work at Mt. Rushmore, unless it's a satellite phone.  GSM 
phones don't work at my brother's house in Temecula (where the heck-u-la), 

A cool thing about my Verizon phone is you can turn on GPSOne and dial 922 
to get your Lat/Lon.  Scroll down on the page for a Lat/Lon of the cell 
tower you are connected to.   It is VERY accurate.

I think around here (San Diego), the people at Qualcomm would tell you that 
CDMA is a better technology.   Having looked at the respective white 
papers, I'd be inclined to agree.  Although the way things are going it may 
be hard to find a new CDMA phone for a while...
