mLock just set the Keylock. The idea is an easier use of the Keylock (especially with N80). Most practical is this tool, when it?s used as the first application by the Active Desk. Instead of open and close the Slider-Mobile or press the ?Profile - Key? you need just to click the mLock icon and the Keylock is set. There are no settings necessary and also no ?application - screens? available.
