Cupertino is on high alert this afternoon after a software update to iOS 8 accidentally removed Cellular and TouchID functionality. The solution? Roll back, and wait until iOS 8.0.2.
Apple got in touch this afternoon to tell us that it is "working around the clock" to build 8.0.2 so users aren't stranded without their phones.
If you installed iOS 8.0.1 and found Cellular and TouchID functionality vanish, Apple wants you to re-download iOS 8 and roll it back.
Here's the full statement from Apple:
We have a workaround for iPhone 6 and iPhone 6 Plus users who lost cellular service and Touch ID functionality today after updating to iOS 8.0.1. Affected users can reinstall iOS 8 through iTunes, for more information visit [Apple Support]. We apologize for the great inconvenience experienced by users, and are working around the clock to prepare iOS 8.0.2 with a fix for the issue, and will release it as soon as it is ready in the next few days.
Apple has also said via its support page that iOS 8.0.2 will restore Health functionality, also.
