iOS 11 is set to launch Apple makes iOS 11 available as a public beta, which means anyone with an Apple ID can install it for free., but if you can't wait for the new operating system, you can install the beta now.
But first, a word of caution: as with any beta software, iOS 11 is not a finished product. There will be bugs and odd behaviors. Some of your apps might not work right. There may be some freezes and crashes along the way. It's a beta, after all.
Apple releases betas to get feedback from users so it can iron out the kinks before releasing the final version. So, if you aren't up for the occasional hiccup, don't install it. If you must, it would be best to install it on an old iPad you have lying around rather than your iPhone that you rely on everyday. .
With that disclaimer out of the way, let's get into how you can update to the iOS 11.
Prepare your device
Next, back up your device. Seriously, do not skip this step -- if something goes wrong, this will be your fall-back. Apple recommends connecting it to iTunes and creating a local backup. Apple also suggests archiving the backup using iTunes. Doing so ensures that you have a good backup stored locally, instead of one floating around in iCloud. Follow Apple's instructions here.
Enroll your device in the beta program
With your device freshly backed up, open Safari and head to Apple's public beta page. Sign in with your Apple ID and then tap the iOS tab. Scroll down and tap the enroll your iOS device link and then tap the Download profile button. Safari will ask to launch the Settings app and ask you to install the beta software profile. Tap Install, enter your passcode and then restart your device when asked.
Download and install the public beta
After your device has restarted and the software profile has been installed, you can now install the iOS 11 beta. Open the Settings app and go to General > Software Update. Tap the Download and Install button if the beta doesn't automatically begin installing. After the download is complete, tap Install Now to install it. It'll take a bit of time to download and install, but then you'll be ready to discover the.
And should you discover a bug with the beta, you can help Apple polish the final version of iOS 11 by reporting any odd behaviors and crashes using the new Feedback Assistant app that gets installed along with the beta. Look for its purple icon.
