Step 4: Make a Backup
iOS 9.0.2 is a small update but you should still make a backup of your device. You know, just in case something goes horribly wrong during the installation process. You don't want to lose precious files or data.
We've put together a guide that will take you through the backup process on iTunes and the backup process via iCloud.
This step might seem like overkill but you'll want to be smart about this update, especially if you're coming from something older than iOS 9.0 or iOS 9.0.1.
