(Update: 1:32PM CT) – Apple says that it is investigating reports of the problems, and has pulled iOS 8.0.1 in the meantime.
The release of iOS 8.0.1 this morning is bringing in reports of a number of users finding their iPhone 6 and iPhone 6 Plus handsets reporting “No Service” messages, along with a non-functional Touch ID sensor.
MacRumors reports that the issues appear to be limited to iPhone 6 and iPhone 6 Plus devices, however the devices are not limited to one specific carrier, with users reporting problems on AT&T, T-Mobile, Verizon, and Sprint in the United States. Rogers subscribers in Canada, EE subscribers in the United Kingdom, and Vodafone subscribers in Germany are also reporting issues..
Restarting the device doesn’t fix the issues, nor does attempting to “Reset Network Settings” in the device’s Settings.
Some users have reported restoring iOS 8.0.1 via iTunes, or doing the initial update via iTunes fixes the cellular connection issues. Apple Support recommends restoring iOS 8.0.1 via iTunes to fix the issues.
The problems appear to be limited to the latest generation iPhone 6 and iPhone 6 Plus handsets, as users with an iPhone 4s, 5, 5c, or 5s haven’t reported any issues. iPad users have also reportedly had no issues.
