Key Lock Clock by Dr. Jukka Silvennoinen is a freeware Clock screensaver application that is shown while the device’s key lock is on. The idea was inspired by the feature found from E71 & E66.
As additional feature this application also includes automated key locker, if this feature is needed, just set it on and set the timeout for idle time out(when user is not interacting with the device) for automatically locking the keyboard.
This version was designed 5th edition touch devices such as 5800 & N97 in mind, but should work just as well with all Symbian S60 3rd edition non-touch devices.
