We've put together an in-depth video showcasing many of the new iOS 9.3 beta 1 features. I think it's safe to say that this release packs in many more features for a minor version release than we're used to. In this video, we showcase the new Touch ID security option for the Notes app, the new quick action 3D Touch shortcuts, updated News app features, multiple Apple Watch pairing ability, and much more.
It looks as if iOS 9.3 beta 1 has already been jailbroken, which lends hope that a public version of an iOS 9.3.x jailbreak may be possible. But don't hold your breath; this is the same hacker/developer—Luca Todesco—that recently shared a screenshot of a jailbroken iPhone 6 running iOS 9.2.1. He previously made it clear that he has no intention of sharing, and it doesn't look like that's changing anytime soon.
It's a big day for Apple beta releases, as is highlighted by the seeding of iOS 9.3 to developers. iOS 9.3 is a major new release that incorporates tons of new features to iOS. Outside of a major version number update, this update is one of the biggest iOS updates that we've seen in a long time.
iOS 9.3 contains a new Night Shift mode, which basically Sherlock's f.lux, along with new Touch ID security options for the Notes app, improved CarPlay functionality, an upcoming Multi User mode for schools, and much, much more.
Put it this way, this update is so big that Apple has devoted an entire web page for previewing many of the new features. That's something that it usually only does for major version number releases, but the content contained in iOS 9.3 apparently warranted the fanfare.
