When I was in the Navy, the policy of Electric Boat (manufacturer of USN’s submarines) was if you wanted to bring a phone anywhere near a boat, it couldn’t have a camera. However, they would also accept permanently disabling it. A shipmate took his shiny new BlackBerry Storm, hole-punched the camera, and got security to sign off on it.

The Navy took a dimmer view of things, and forbade any phone in the engine room (which is where the nuclear reactor is controlled), camera or not. For a brief period of time, it was being discussed that they would also ban eReaders anywhere, but that didn’t get traction while I was in. I have to imagine things have gotten stricter if anything, given the capabilities of modern devices.
