A colleague of mine at work has the Tmobile G1, and today we were comparing applications just to burn some time and he showed me an app called MeetMe
http://www.androidapps.com/t/meetme
It is basically like a social networking app that lets you see who is around you based on their GPS location. People can post their pictures, names, gender, about me info, etc... and you will be able to see and messages to a person thru the app.
Is there anything like this for the pocket pc?
Thanks
