Vibrate driving me crazy

[srtpusher]

ok..

i have read a bunch of ways to change the vibrate but i cannot find a way to do this.

i have a 30 sec ringtone. i want the phone to vibrate 3 short times, pause, then 3 short times again while the ringtone is playing.

i can only get it to vibrate either one long time while the song plays or once before, then no vibrate for the rest of the song.

any help?
