Mute Korean/Japanese shutter sounds

I currently live and bought an iphone in Korea which doesn't allow phone cameras to be muted in any circumstances.

However I plan to return home and was wondering if I could remove the shutter sounds since the laws don't bound them anymore.

I understand that it is somehow coded into the device, so if I go to the Apple service center, will they be able to do anything for me?

I am even willing to pay if necessary.
