This how-to is excellent but could be improved with discussions of Taptic engine cable techniques and best practice with the iFixit replacement battery. It took me close to 30 minutes to get the Taptic engine connector set properly (finally did it with jeweler's flathead screwdrivers to line it up). I also couldn't figure out the wrapping for the battery and ended up tearing it apart. I also wasn't sure about battery placement so that the connector cable would fit properly. Used a silver Sharpie to mark a line on the battery and beside it so that I got it in the right spot once the adhesive backing was removed. Finally, a small metallic fitting popped out of somewhere when I got the last battery adhesive loose. Was confusing for a minute, but I finally decided the piece fit best under the Taptic engine 2.1 Phillips screw. All in all, excellent directions! Thank you.

Has anyone found the polycomm software?
