iOS 8.0.1 release notes

* iOS 8.0.1 “No Service” After Installing and Touch ID Problems Reported

Many users who installed iOS 8.0.1 have reported problems with cellular service and cell connections, in addition to problems with Touch ID immediately after installing the update. Notably, iPhone 6 and iPhone 6 Plus users have experienced a persistent “No Service” cellular signal failure. Touch ID has reportedly stopped working for many users, though which devices are impacted by the Touch ID failure are not yet known. At the moment, it seems like iOS 8.0.1 introduces more bugs than it fixes, so users are strongly advised to avoid the update.

If you already updated to iOS 8.0.1 and are stuck with No Service, here’s how to fix the problems until Apple releases an updated version.
