Apple releases iOS 8.0.1, users report major problems with update
 

One week after the launch of iOS 8, Apple has already released its first update for the new OS in iOS 8.0.1, which contains a slew of bug fixes. But you shouldn't hit the install button yet. Soon after the update hit, an abnormally high number of users immediately started reporting that the iOS 8.0.1 update is breaking cellular reception and other features like TouchID. For those affected, "no service" is displayed after the update has been installed, and toggling airplane mode or powering the phone off and on again doesn't seem to be fixing it. We've reached out to Apple for comment on the situation. Do not install this update. There's no way around it - these issues are very widespread. The iOS developers and ordinary users in my Twitter timeline are not pleased right now.
