"Our new electric clothes dryer came with instructions on how to connect it to 3-wire service. Red to hot, Black to hot, white to neutral, and a jumper from the frame of the dryer to the same lug the white wire is on."

I saw a video (the "Internet Electrician", I believe) explaining this option. He advised best practice is to properly convert the receptacle to 4 wire, but acknowledged properly converting the appliance plug to 3 wire was sometimes appropriate.
