However, since the software is still in development ahead of the full release expected in September, it may be a little buggy at first. Apple recommends that users back up their phones before upgrading, and if possible install it on an iOS device that isn’t their main iPhone.
If you’re still happy to install it, here’s how:
iOS 11 is available for the following:
- iPhone: 5s, 6, 6 Plus, 6s, 6s Plus, SE, 7, 7 Plus
- iPad: 5th generation (2017); Mini 2, 3 and 4; all Air models and all Pro Models
- iPod Touch: 6th generation (2015)
To create an archived backup of your device, you connect it to iTunes, select your device and then “Back up now” Make sure you have ticked the box to encrypt your backup.
From there go to Preferences in the iTunes menu and find devices. Find your recent backup, right click and archive it. This will mean it doesn’t get overwritten by new backups.
