iOS 8's first update appears to be breaking both cellular service and Touch ID on iPhones, and restarting the devices doesn't fix it.



From TUAW:

Multiple users on social media are reporting the bugs and our own Steve Sande has fallen victim to the unfortunately busted update as well, with an iPhone 6 now incapable of receiving a cell signal and a home button fingerprint sensor that doesn't function as it should.

  Warning: iOS 8.0.1 seems to be breaking iPhones
