I was just wondering (and I'm sure many others have) if a program exists to use the camera as a lock button app (the volume rocker would do, also). Before creating this topic, I did some extensive research. I downloaded an app called ScreenModeWidget for free on the Market. Unfortunately, I could not get this app to work. Second, I understand the fact that the power button is hard wired, and to change the power signal to another button is impossible. What is possible, though, is either a third party lock app or (maybe root required) an app that changes the "lock button" to either the camera, the rocker button, or both. Does anyone know if one exists? Thanks! EDIT: I also wanted to mention that I tried Lock 2.0 free, also.
