Gps not working on 3.0

[lordzod01]

I have a 3g upgraded to 3.0 and my gps is not working. I get the message could not find your location. Maps works for route finding but I don't get the moving dot anymore.

I use this alot so I was wondering if anybody knows how to fix it. I have restored twice allready and reset the iPhones settings to default, to no end.

Anybody got anything on this?
