Apple Seeds Fourth Beta of iOS 9.3.3 to Developers and Public Beta Testers
Today's iOS 9.3.3 beta update can be downloaded from the Apple Developer Center (developer only) or over-the-air with the proper configuration profile installed.
As another minor 9.x.x update, iOS 9.3.3 features under-the-hood bug fixes and performance improvements to address issues unearthed since the release of iOS 9.3.2. No outward-facing changes or obvious bug fixes were discovered in the first three betas of iOS 9.3.3.
iOS 9.3.3 beta 4 follows the developer launch of iOS 10, a new version of iOS that will be released to the public this fall. iOS 10 includes features like a redesigned Lock screen experience, a revamped Messages app with its own App Store, a Siri SDK for developers, a new Home app for controlling HomeKit devices, a redesigned Apple Music app, and more.
