I second Matt's suggestions. I, too, have had the late TXTs and on rare occasion a call not coming thru and that has followed me thru my entire phone history (MotoQ, then Mogul, now Touch Pro). If you're having problems with both TXT and incoming calls, there may be a legitimate issue with the phone. Have you flashed any ROMs or Radio updates at all? If not, you may very well want to take it to a sprint store w/ a repair center that can test to see if your phone is sending/receiving signal correctly. If you have flashed a ROM or Radio, you may want to flash back to stock just to make sure.
