I have a gtran 4020 here, and i need to make the incoming sms alerts silent
it's in slient mode, and sms->alert type is set to "Vibrate".
i've also tried with alert type set to "Light"
but it still makes the jolly chiming sound.

i'm testing a sms system and it's driving me nuts~!!!! (and everyone else in the office)
how do i make it shutup?
