Hi i'm still a BB noob.

I just got my bb two days ago. At first GPS and TCP (opera) internet didn't work. Then from this forum I updated the firmware and everything did work. Today I upgraded the desktop manager to the latest version and GPS and TCP stopped working. I'm not sure exactly why but I think my best bet is to restore my O/S or firmware to the factory default, then install the firmware upgrade again (and not the new desktop manager). But I don't know how to do that. Can you all help?

Thanks,

Chris
