Claim:
1. A method for providing security on a mobile communications device, the method comprising: forcing the mobile communications device into a locked state, regardless of any current user input activity and regardless of wireless network coverage, upon expiry of periodic timeout periods, each timeout period having a first duration; detecting, by a communications subsystem of the mobile communications device, prior to expiry of a particular timeout period of the periodic timeout periods, a lack of wireless network coverage for a second duration that is shorter than the first duration; and responsive to detecting the lack of wireless network coverage for the second duration, forcing the mobile communications device into the locked state prior to the expiry of the particular timeout period, regardless of any current user input activity, thereby shortening the particular timeout period from the first duration to the second duration.
