here is an OTA link to a program called autolock
http://www.geekandproud.net/blackber...k/autolock.jad
"AutoLock
AutoLock automatically locks the BlackBerry keyboard after the backlight turns off, optionally waiting a configurable delay after the backlight shuts before locking the keys.
To enable/disable or set the delay, go to Options->AutoLock."
i havent tried this on the storm, but im sure it will work. you might need to disable compatibility mode
