If you have just updated your trusty iPhone to the just-released iOS 8.0.1, chances are you may have ended up with a device that can't connect to the cellular network (shows No Service in the status bar) or read fingerprint data through the Touch ID sensor on the iPhone 5s, iPhone 6 and iPhone 6 Plus. As you could imagine, social media is awash with complaints from disgruntled users who are venting their frustration over the cellular and Touch ID issues.
At any rate, your best bet is to steer away from this update until Apple address the situation and releases a fix. Not everyone is affected, of course, but keep in mind we have no real indication as to how widespread those issues are because Apple, at the moment, isn't talking much.
That's why we're asking you, our readers, to tell us whether iOS 8.0.1 has broken cellular connectivity and Touch ID for you.
