I updated to iOS 8.0.1 at about 1:00pm EST and like everyone lost my Cell Service and Touch ID. I contacted Apple Support and they had me setup my iPhone as new. To make a long story short, the process somehow created a nightmare in that my 7,300 photos did not load to my iPhone. It is now 11:00pm and I finally have my iPhone back to normal with all Photos, Music, Apps and other Data. Unfortunately during this afternoon's fun I had to load from a Backup created from my former iPhone 5. Now I have the iPhone 6 "Screen Sensitivity Issue" back ...but I am not going to try and resolve that until tomorrow. Good luck to all that have unfortunately updated to iOS 8.0.1 I hope you get back to iOS 8.0 without too many hours of Backing up, Restoring, etc. etc.
