I did this tonight, took about 45 min. I used my iFixit tool kit to all the work.
When putting it back together I had an issue with my screen going all "white lines", turns out it was just a loose connection on the digitizer cable, I lifted it and placed it again and all is good with the world.
I had to replace the assembly because I was getting feedback when making calls with headphones and no voice at all with headphones if the phone was plugged into power. Now I can do both.
Thanks so much iFixit for making this possible.
