Is there an App or Widget that can replace my Screen On and Off Button on my Moto Droid? The button is broken and I'm waiting for my replacement phone.  I can turn it on by sliding open the keyboard but I have to wait for it to sleep to turn the screen off.  Is there an app or a shortcut that I can put on the home screen to do this? Or maybe a hack to change my camera button to a screen off button?  It's an un-rooted Motorola Droid 1 running 2.2.
I ended up using this free app: http://code.google.com/p/lockenabler/ and with smart bar I was able to set the camera button as a shortcut. My cam button now turns off the screen on a long press.
