When I couldn't find it, I learned to live with it, and then decided I liked it. 
I like that app, but on this phone, the optimus M I dont use it.Also there's an an app called no lock where you can enable /disable locking right from the home screen with one click.
Does anybody know how to get rid of the dreaded "big grey lock" that appears on this phone? I was able to change settings to "end call with power button" but had a terrible time trying to access the dialpad when listening to my messages. You can't!!!! I had to reverse that and go back to using the on screen end call button. I HATE the big grey lock and would love to get rid of it.
