Im not a blackberry expert, but I develop for iOS and Android. The on/off switch or power button is hardly linked to the device, and the action performed when it’s pressed is written in the operating system, not in an application, I don’t think you’ll find an event listener for this button to be pressed, just imagine the security issues it could raise if an app could prevent the phone from turning off (or on …)
