Kill all running apps

Hello, I need an app for Symbian Belle, which closes / kills ALL running apps that are viewable in the Task Manager. Whilst Symbian Belle can do this natively, it doesn't kill the Telephone/Dialler app (which is still viewable in task manager, even after all apps have been killed). So your solution must kill all open applications viewable in Symbian Belle native task manager. Please name your app, "Kill Apps" Many thanks.
