That's bizarre... you're not even rooted anymore, I take it? Did you do a full factory wipe after going to stock ROM (it's probably redundant, but what the hell)?
There's one other possibility -- it happened on my BlackBerry a few years ago and I got a strange error (dunno if Android gives that sort of error or where) -- basically, I had a bad SIM that still worked (it just couldn't connect, but the phone saw it as a normal SIM). I replaced it, called T-Mo and gave them the new SIM number (you can do it online nowadays) and was back up and running in minutes.
Of course, try pulling out the battery, SIM, and SD card, then put everything back in and power on...
