Me and the wife just got droids and we're absolutely loving them so far. I have done a lot of research and I'm able to rip/convert videos to put on my droid - however one thing bugs me, it is WAY to easy to screw things up by bumping it with my fingers. The search, home or just on the screen. Is there a program, or any way to (without rooting) get it to essentially lock the screen and require a press of the power/lock button to unlock it. My nephews want to watch videos but I don't want them accidentally getting out of the video and screwing with the phone or calling someone. Any help would be greatly appreciated.
