Update to iOS 8.0.1 creates problems for Apple iPhone 6 and Apple iPhone 6 Plus
Some Apple iPhone 6 and Apple iPhone 6 Plus users who have updated to iOS 8.0.1, are wishing that they had passed on installing the new build on their phone. Apparently, the update is preventing these iPhone users from connecting to the network used by their carrier. Others are having issues with Touch ID. While Apple will no doubt send out another update to fix the problems, there is a solution.
First, you will need to turn off Find My iPhone. Go to ipswdownloader.com and download the proper version of iOS 8 that you will need. Make sure you have the latest version of iTunes running. Launch iTunes.com on your desktop computer. Take your Lightning to USB cable and connect your iPhone to iTunes. Hold down Control (PC) or Option (Mac) and click on "Check for Update". Choose the iOS 8 firmware file you selected from ipswdownloader and let nature take its course.

Once you have your iPhone 6 up and running, don't forget to turn Find My iPhone back on. If this method isn't working, you can try a full restore, or wait for Apple to send out a fix.
