Fix Cell Service & Touch ID After Installing the iOS 8.0.1 iPhone Update

The official release of iOS 8 was highly anticipated, but the truth is it may have been a little premature on Apple's part. Since its debut only a week ago, plenty of bugs and issues have been reported across the various compatible iPhone models.

Just seven days after iOS 8 came out to the public, Apple released an 8.0.1 update in order to address certain bugs and improve iOS 8 for consumers—unfortunately, it only made it worse.

What the Update Was Supposed to Fix

The issues Apple addressed with the update were made to improve known bugs with third-party keyboards, compatibility with HealthKit app, and problems with apps having access to the Photo Library. The full list of improvement can be seen below.
