SAME PROBLEM. Started this past week. Was fine for months on TG reloaded.
I was thinking it was new app related, but you wiped and still have the problem?
I'm not going to wipe if you already tried it.
I'm going to try turning off EVDO and see what happens.
edit: INSTANTLY dozens of missing texts sent/received when going from EVDO only to CDMA only mode!
I am pondering if flashing back to stock ROM and re-running Virgin Activation app would help....
Damn I wish you could run Activation in CM7
