Apple has finally started rolling out the iOS 11 Public Beta software and it's now ready to download for users. iOS 11 was introduced at the Apple's annual Worldwide Developer Conference (WWDC) earlier this month and the developer build was launched before this Public Beta.

iOS 11 Public Beta is now available for users and is compatible with iPhone 5S and above models, iPad 5th generation and above and iPad Touch 6th generation.

Here is how you can download and install the beta version on your iPhone or iPad:

Before downloading any beta software always remember they are far from being perfect and may also crash your system. It would be best for you to keep a backup prepared on iTunes for all your data on your iPhone or iPad before installing iOS 11 Public Beta software. Apple advises that you test the beta version of iOS 11 on a secondary device.

"We strongly recommend installing beta software on a secondary system or device, or on a secondary partition on your Mac," says the company.

First, you have to enroll for the new iOS 11 program. Apple users need to go to First, you beta.apple.com and register their devices. Here you will have to log in with your Apple ID and then Apple will ask you to accept a long agreement in order to enter the iOS 11 Public Beta program. After you accept the terms and conditions, your Apple ID will be added to the program. Here you will find tabs for iOS, macOS, and tvOS. On top are tabs called Guide, Enroll Your Devices, Provide Feedback, FAQ and Sign Out. Click on enroll your devices and choose iOS 11.

After the signing up process is completed you will have to open your iOS device which is compatible and eligible to get the iOS 11 update. Open Safari browser in it and go to beta.apple.com/profile. Once again, you'll be asked to sign in. If you've already enrolled in the program on a desktop browser, you should see the configuration profile for iOS 11.

Now the device will direct you to install the configuration device. Follow the instructions that will come onscreen and the installation will be complete. Apple iOS devices, which are on iOS 8.1.3 or later will automatically receive the latest public beta software as OTA updates. All you have to do is, just go to Settings > General > Software Update and install any new beta update that is rolled out during the course of testing.

To get back to the old version of iOS on your device just plug your iOS device into your Mac, and go to iTunes. Pick the last iTunes backup and restore it on your iPhone or iPad.
