Real tough to figure out how this occurred, since I was in the middle of flashing a new rom when the first text arrived. I tried rebooting, tried wiping all data and restoring with clockwork, tried re-flashing the rom and restoring with CWM...nothing worked. The only thing I didn't try was resetting all back to stock since I couldn't stomach starting over with rooting.
I finally just wiped everything and re-flashed the rom (using ACS syndicate fyi) and did not restore. The text still arrived twice in the 1st 30 minutes, but then not again. So, I took the opportunity to clean things up and didn't restore with CWM, just re-downloaded everything. So, about an hour later, everything was re-installed and back the way I like it, and the text stopped coming.
Most likely, it was a sprint data problem and all the effort was for nothing. but at least I cleaned out some programs I rarely use.
