So I just got the phone and wondering this question:
My old phone that I had, had a simple button that set everything to silence or everything to vibrate, on the storm i've noticed the sound features, but if I set it on vibrate or on silence, will EVERYTHING be on vibrate or silence, since i'm a highschool student and I really wouldn't like it going off in class..
I created my own "vibrate" profile where I set everything to vibrate. You can set how it vibrates such as long pulses or short vibes and also how many times it will vibrate. You may find this useful.
