Is it sold in Japan? I have a Sharp camera-phone, and in manner mode it does make a sound when taking any picture - except for the OCR and business card reading modes, in which it's impossible to save the image anyway. I found it inconvenient when I was at university and wanted to take the blackboard... I've seen silent regular cameras, though.
