hi, I have bought an arnova 10 g2 tablet that runs gingerbread firmware. However there is no option in the security settings to activate a screen lock or pattern lock. After reading features of the new android gingerbread this option is supposed to be available but on this tablet it is not!. What is the best 3rd party app that can lock the screen with either a pin or password? Also is there an app that runs at boot so that you have to enter a password before the home screen starts, something similar to windows when that boots. Any help would be greatly appreciated as I cant seem to find any information anywhere.
