Camera - How do I turn off the clicking shutter sound?

There is not an option or setting on the BB to turn off the shutter sounds you hear when you take a picture.

However there are three workarounds to silence the shutter sounds:
Dial a phone number and, while in the call, your camera will not emit shutter sounds.
Plug in wired headphones before taking photographs.
If you have a GSM device, you can use the BerryAnnoying which will disable shutter sounds while the application is running.
