I just got the Droid. On my old phone I use to turn the volume to vibrate or very low at night so if there was a call or txt in the middle of the night I could respond because if its at that hour its likely an emergency. Well with my droid I get facebook and email notifications as well and I recieve those at all times of day and night. Is there an app that when I activate it will deactivate vibrating or ringing for everything except txt msgs or phone calls? It'd be even better if I could pick what would vibrate or ring after I activate the app.
