Apple just announced the release date for its upcoming iOS 12 is September 17th. But you can install the finished version of iOS 12 starting today and gain access to improved notifications, Memoji, Screen Time, Siri Shortcuts, and other new features.
iOS 12 is estimated to improve performance and responsiveness on iPhones both old and new.

The golden master build of iOS 12 is rolling out today to participants in Apple’s beta testing program. So if you want to start using the new update today, all you need to do is join the beta.

1. back up your device while iOS 11 is still on it — just in case. The best way to do this is through iTunes.
And if something goes wrong, that’ll put you in a tough spot. So just do the iTunes method. It doesn’t take long.

How to install the iOS 12 GM release:

Visit (It’s best to do this directly from the iPhone or iPad you’ll be updating to iOS 12.) Choose “sign up,” and log in with your Apple ID. Agree to the usual terms and conditions.

From here, select the iOS tab, where you’ll see the option to download the beta profile onto your device. Do that. Choose “install.” You’ll be asked to enter your iOS device passcode and tap through a few screens.

Eventually, your iPhone will restart. After that happens, you can go to settings, check for an update, and you should see the iOS 12 update come up. Download and install it as you would any other iOS release.
