Before my Motorola Bravo upgraded to Android 2.2.1, I was able to remove the screen lock. It's the lock that requires you to swipe your finger across the bottom after the screen turns off and you turn it back on. There used to be an area in the settings that let me turn that off so that when I turned the screen back on it didn't require me to unlock it, but now that option's gone. Is it possible to remove this lock? It's really annoying.
