Apple started testing iOS 9.3.3 with developers and public beta testers near the end of May, and today the second beta version of the pre-release software has been released for developer iPhones, iPads, and iPod touches. The update marks the first iOS 9.3.3 beta available for the 9.7-inch iPad Pro, which missed out on the first beta version during the iOS 9.3.2 update bug.
iOS 9.3.3 is yet another bug fix update to the feature-packed iOS 9.3 release from earlier this year. iOS 9.3 included Night Shift, Touch ID Notes, Apple Music for CarPlay, and much more.
