Apple has released the second beta of iOS 9.3.3 to developers using an iPhone, iPad, and/or iPod touch for testing purposes. This comes two weeks after the first build of the next software update for Apple’s mobile devices began rolling out.
This update doesn’t bring any user-facing changes, however does include multiple bug and security fixes. The next time we actually expect new features is at WWDC during the debut of iOS 10.
In the previous build, it was discovered that you couldn’t install the software on the 9.7-inch iPad Pro due to certain issues the device had which, since, then, have been resolved. This has led to the release of iOS 9.3.3 beta 2 for the 9.7-inch tablet and includes everything other versions of the build does.
