I'm a new Droid Incredible owner and have a question. Whenever I receive a txt message my Incredible will play the notification I have chosen and it will also vibrate at the same time. How do I shut off the vibration so it will only play the sound? I want it play the sound with no vibrate or vibrate with no sound. I don't think I would ever want it to do both at the same time like it is doing now. Thanks!!
