Now here's an issue that would seem to apply to many users doing this repair: if the screen is nonfunctional, how do you power-off the device? When I dropped my iPhone, the screen went almost completely dark, midnight blue, actually. I can use the power button at the top of the phone to turn the display on and off, but I can't get the phone to power off. Seems the only way to do it is to wait until the battery is exhausted.
