Apple is launching a public beta for iOS 9 in July, similar to the early testing it allowed Mac owners to participate in prior to the release of OS X Yosemite. The expanded field of beta participants is no surprise considering the focus that Apple has reportedly put on squashing bugs and optimizing performance with iOS 9, which is slated for release this fall. Apple's Craig Federighi said the goal of iOS 9 is to "elevate the foundations of the platform" with a focus on fundamentals like battery life, performance, and security.

Update: Read the iOS 9 review.

But there are new features that beta users will be able to try out early, like the revamped, smarter Siri personal assistant, public transit directions in Maps, improved QuickType keyboard, a more robust Notes app, and split-screen multitasking support on iPad. If you're interested in participating, you'll be able to register for access at Apple's beta website today.
