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 cellular networks, at least in the US, and is also breaking other features like TouchID. We have confirmed those two problems, and we're investigating what else might be wrong.
Update: Apple has advised us as of 4:15pm AEST that it wants users to roll back the update and wait for iOS 8.0.2 in the next couple of days. More here.
We've updated two iPhone 6 models 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 a 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, but it's unclear right now if the reception issues are only affecting the US only.
After the problem was discovered, Apple quickly pulled the update.
We've reached out to Apple for comment. We'll update 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.

Australian note: we haven't confirmed whether any Australian users were affected by the possible mobile network issue with iOS 8.0.1. We'll let you know!
If you have updated to the new version on iPhone or iPad, please let us know what you are seeing in the comments.
