CallWave quiets untimely ringing

It never fails--a cell call comes in at the worst possible time. You don't want the phone to disturb others in the theater, movie theater, meeting, church service, or other quiet place, but you don't want to miss critical calls, either. Enter CallWave, which converts voice messages to text messages and sends them to your phone.  Just make sure the announcement for SMS is set to "vibrate," and you're good to go.
