A Quick fix for iOS 8
DON’T PANIC EARLY IOS 8.0.1 UPDATERS – HERE’S THE FIX:
If you updated immediately before hearing about the problems with iOS 8.0.1, here’s what to do.
Connect your phone to iTunes and back up your data. Then, click the “Restore iPhone” button and follow the on-screen instructions. I know this is a terrible pain, especially mid-workday, but at least it’s better than having your iPhone turned into an overpriced iPod touch.
For those without access to a computer with iTunes right now, you’re unfortunately out of luck. I’ll update this post if anyone finds a way to fix the issue without a computer handy.
