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
BerryBuzz extends your default Blackberry alert system. BerryBuzz allows you to customize the LED color for many alert types and keeps the LED flashing for longer than the default 15 minutes your BlackBerry does.
It will repeat alerts until acknowledged so you will never miss an alert again.
Plus it adds customizable vibrate for incoming calls
