My wife had managed to shatter the rear glass panel pretty badly, so I was looking for an OEM part to replace it with. A quick search on the net led me to ifix it.com. The part came in super quick and the guides along with watching some videos helped make this repair go smoothly and quickly.
I'm really glad I was told during the ordering process to order the special screwdriver needed to unscrew the rear panel. The whole replacement process was very easy for me (first time ever) and I had the old panel off and the new one on in about 20 minutes or so.
Watch the videos and read the guides before you start. Very beneficial and it
made the process quicker in my opinion.
