Solution worked very well - a couple of comments: 1. With a cracked screen the suction cup doesn't hold very well, I was nevertheless able to get the screen corner off with some heavy prying above the headphone jack as suggested in step 4. 2. In the replacement part I received, the order of the digitizer and camera cables was reversed, I had to tuck the digitizer cable back under the camera cable to get them down in the correct order. Great pictures and guide from ifixit.
