When the phone is introduced to power such as a USB or AC power cord, It auto powers on. I just leave it on 24/7 but the program I listed above helps me out when I need to reboot the phone safely without having to yank the battery and reconnect to a power source to start the phone again.
I plan on in the future to fix the power button but right now it works just as good with the Cyanogenmod 7 RC1 and it has volume wake when the phone goes into standby.
hell for 25$ You cannot beat it!
