Yesterday, Apple released an update to iOS 8 intended to squash some bugs, including HealthKit apps, third-party keyboard issues, and missing photos from the iPhoto app. Within minutes of the download going live, Twitter was buzzing with news that the update disabled cellular networks and broke Touch ID on a variety of devices.
Apple pulled the update shortly thereafter. However, hundreds of people had already finished the update and were now holding a useless device in their hands. Last night, Apple posted a support document, explaining how to downgrade back to iOS 8 and promising a new update within the next few days.
