Wi-Fi seemed to be one Apple’s biggest focuses with the most recent iOS 9 Public Beta release. While the last release was more about bug fixes and performance enhancements, iOS 9 Public Beta 3 adds a bunch of new features like Wi-Fi calling support for AT&T and Wi-Fi Assist, a new feature that enables iPhones to switch over to a cellular data connection when the Wi-Fi connection they’re using isn’t very good. 

For the first time, Apple this year allowed the public to participate in beta testing the forthcoming version of its new mobile operating system, iOS 9. And now, the company has pushed out the latest release, iOS 9 Public Beta 3. The update comes only only a few weeks after the Public Beta 2 build, which largely included bug fixes and speed enhancements. But this time around, beta testers will have a number of new features to play with including, most notably, the addition of Wi-Fi calling support for AT&T, CarPlay enhancements, a whole slew of new wallpapers, keyboard tweaks, Wi-Fi Assist, and more. If that last one sounds familiar, it’s because Wi-Fi Assist recently debuted in the iOS 9 Developer’s Beta 5, which is actually the same code that’s now available to public beta testers, as well. In case you missed it, Wi-Fi Assist is an especially handy new feature that will enable the iPhone to switch over to the cellular data connection when the Wi-Fi connection is shoddy.
