[Az-Geocaching] GPS cell phones

I'm sitting here this morning listening to KFYI radio, and the subject is GPS cell phones. It appears a lot of people are concerned with privacy: Wives and husbands keeping track of their spouses, and BIG BROTHER monitoring the users, etc. I'm curious if anyone on this listserv has used these phones and what they feel about them!?

Here's a few sites:
