Hmm, well that didn't take long.
I installed the new ROM (skipped customizations), ran my SPB Backup restore, waited for the phone to boot up.
After it came back up, I have *no* service (usually I have 1 bar of roaming in the office), and while I was in the Comm Manager trying to figure it out, first bluetooth just turned off, then the phone hung right there in comm manager. No going to sleep or anything... just stopped responding with the screen still on (wouldn't even turn the screen off when I pressed power!).
Guess I'll go to one of the custom roms. Too bad
