Here’s a copy of the Verizon Droid manual in PDF format. You can either view the manual here or click to download a copy to your computer.
Strangely the manual seems to acknowledge that the Droid cannot be turned off while connected to a power supply. At first I thought this was a bug but page # 3 of the manual clearly says “your device is always on when being charged”.
Naturally you’ll want to be sure to add Google Voice to the Droid which in turn can give you unlimited free incoming and outgoing calls (assuming you have the friends and family option). See Lifehacker’s article on how to setup Google Voice for “free” unlimited calling.
