If something goes wrong during beta testing and you don't have a backup, you may not be able to return to iOS 11 or iOS 12.2 without losing everything on your iPhone. But if you're going to make the dive into iOS 12.4 beta, you'll want to keep a backup of your iPhone as it currently stands. If your experience with iOS 11 or iOS 12 was buggy, you might want those days to be far behind you. In these instructions, we'll assume you're updating an iPhone, but the process is the same for all compatible iOS devices, i.e., a compatible iPad and iPod touch.

The first beta will be made available to the public on May 20 via Apple's Beta Software Program. Released first to developers on May 15, just two days after iOS 12.3's stable version was available to the masses for iPad, iPhone, and iPod touch, iOS 12.4 includes the beginnings of Apple Card. If you want to try out all its new features before everyone else, you can install the developer or public beta on your iPhone right now. However, some brand new features can be accessed with Apple's latest beta, iOS 12.4.


17, and most of the announced features have been released for the iPhone's latest available operating system.
