New iPhone owners: do not update to iOS 8.0.1 yet. The upgrade iOS 8 that just rolled out over the air is killing the ability of phones to connect to mobile networks and is also breaking other features like TouchID. We have confirmed those two problems, and we're investigating what else might be wrong.
If you're having the problem, here's how to fix it.
We've updated two iPhone 6 models [in the US] to iOS 8.0.1, and both cannot connect to the carrier and display "No Service". Additionally, the update breaks TouchID so you can no longer get into your phone with your thumbprint. One of the phones is regular model on Verizon, the other is an Phone 6 Plus on AT&T. So this is hardly an issue isolated to a single phone model or carrier.
After the problem was discovered, Apple quickly pulled the update.
We've reached out to Apple for comment. We'll expand on the issues as we learn more.
iOS 8.01 is completely breaking your ability to connect to the cellular network, so you might wanna hold off on that.

iPhone 5S back up and running under 8.0.1. Cellular connectivity good, Touch ID still works. Still don’t recommend this update for anyone.
