Apple has just released the final version of iOS 12. This update is all about making your phone work better — and there are also a bunch of new features. The update is currently rolling out and is available both over-the-air in the Settings app, and by plugging your device into iTunes for a wired update.
Many people try to download these major updates at the same time. Apple usually implements a queue system to ensure speedy downloads once you’re at the front of the queue.
iOS 12 is compatible with any device that can run iOS 11 — the iPhone 5s and later, the iPad mini 2 and later, the iPad Air and later as well as the most recent iPod touch.
But first, backup your device. Make sure your iCloud backup is up to date by opening the Settings app on your iPhone or iPad and tapping on your account information at the top and then on your device name. Additionally, you can also plug your iOS device to your computer to do a manual backup in iTunes (or do both, really).
Don’t forget to encrypt your backup in iTunes. It is much safer if somebody hacks your computer. And encrypted backups include saved passwords and health data. This way, you don’t have to reconnect to all your online accounts.
Once this is done, you should go to the Settings app as soon as possible to get in the queue. Navigate to ‘Settings,’ then ‘General’ and then ‘Software Update.’ Then you should see ‘Update Requested…” It will then automatically start downloading once the download is available.
