Try out the iOS 11 Public Beta /
Alan Stonebridge shows how you can take the new features in the next update for a spin.
Install the tvOS beta
Installing the public beta of iOS 11 is actually very straightforward, though it’s best to install it on a device you don’t depend on on an everyday basis — say, to check your bank account and pay bills. You can restore your device back to iOS 10 if you want to — or at least you can until a short time after the final public release of iOS 11, though Apple doesn’t say exactly when.
BACK UP FIRST
If you decide iOS 11 isn’t for you, make sure you roll back as soon as you can spare the time to do so. Note that the process takes longer to complete than simply telling a Mac to switch from starting up High Sierra from one partition to using your previous system on another.
As always with a big software update, the first thing you should do is make a backup of your device. On iOS, you might already be doing this using one of two methods: using iOS’s iCloud Backup feature, which backs up automatically when your device is locked, on Wi-Fi, and connected to a power source; or using the device backup capability of iTunes on your Mac.
