We've said this many times already but we'll say it again. A little preparation ahead of a new iOS update can prevent problems and the headaches that typically come with those problems.
We've put together a step-by-step process that will walk you through the steps we typically recommend ahead of an install. We've refined this walkthrough over the years and its come in handy for us and many others.
