Over the last two days or so, my radio has been intermittently switching back and forth between GSM (stays that way mostly) then GPRS/EDGE (minutes). I have called my carrier and they said everything's ok--my location, provisioning etc. When I hook up to WiFi at my friend's house (I still don't have Internet at the new apartment ), everything works. So that means my PIN is still "seen" except that I am on GSM mode for the most part.

Out of frustration and desperation, I'll be wiping this clean and reinstall. But before I proceed, do you guys have any other suggestion for me?
