GSM BlackBerrys generally have the capability to silence the shutter. The only CDMA BlackBerry with that ability at this writing is the Tour. There is a work-around with the 8330 that involves calling your voice mail and taking the picture, but it doesn't completely silence the shutter.

i do not think there are any laws that say the phone has to make the noise, my last phone didn't make any noise, also my digital camera can be silent, whats the difference?
