So for you iPhone users in case you haven't heard by now, DO NOT upgrade to iOS 8.0.1 though by now you shouldn't even have the option because they say it's been pulled. If you downloaded it, don't install it. It actually broke the network connection and a few other options like Touch ID. I don't get it. Don't they test these things? I am surprised they wouldn't have noticed the errors themselves since it was so widespread with the initial release of the update.

EDIT: I should specify these issues are mainly effecting the new iPhone 6 models.
