iOS 12 Beta 3 has been released for registered developers. iPhone and iPad users can download the update over the air.

Although iOS 11 is the current public release, but all eyes are fixated on iOS 12 at the moment and what it will bring to the table. Of course, the software is currently in beta and can be downloaded directly from the Apple Developer Program website which requires a paid membership or from the Beta Software Program which is absolutely free. Be warned though, this is beta software we’re talking about here, which is absolutely unfinished in every way imaginable.
