I have looked and failed to find the setting to lock the keypad after the blackberry is inactive. If someone knows this, it would be much help to me! Thanks

AutoLock automatically locks the BlackBerry keyboard after the backlight turns off, optionally waiting a configurable delay after the backlight shuts before locking the keys.
There is an OTA download. I've been using it on my 8350i for about a month and it works great. By the way, I did not have to use the OS 4.5+ fix referenced at the top of their page - it just worked via the OTA download.
