First for Apple: Public Beta for iOS 9, starts in July

Starting in July, Apple will make an official, 'Public Beta' available to everyone willing to test the new software. Public betas aren't 100% new to Apple, as the latest iOS 8.4 builds are available to the public for previewing, but we've never had the opportunity to test out a major new release. In any case, the exact launch date of the program hasn't been specified, nor the list of devices that will be eligible to participate (we suspect all devices currently supporting iOS 8, meaning all iPhones from the 4s to today), though we expect an early July release. We also expect that Apple will make it easy for consumers to go back to the safety of iOS 8. 

As you can guess — and this will probably be made perfectly clear to consumers about to enroll in the Public Beta — the test software is likely to be at least somewhat unstable. So if you do decide to take part, you better be clear on that.
