Before we get into how to download it, we’ve got a pretty big disclaimer for the newbies out there: Software updates are often unstable. If you download iOS 9 on the first day or on an older device, you may experience random crashes, weird reactions from apps, battery drain, and other issues. That said, iOS updates aren’t typically too crazy, so you should be fine. Just know that there is a risk of performance issues with new software.
If things get too hairy, you can always downgrade back to iOS 8.4 (we’ll tell you how — Apple’s got a nice guide setup, too). Now — on to the good stuff.
