 So this is really just a preview of some of the new things coming to the iPhone later this fall, but for free. You can install it on your iPhone now if you're willing to maybe deal with some bugs and try things out early before they're really polished and ready for everybody to use. Yeah, so Apple has made it much easier in recent years for the average person to install this, the beta. It's very, very simple. So what is the caution here? You can't just go back if there's a problem, right?
