Apple has finally released its first public beta version of the new software iOS 9.2. We know that this build went out to the developers first a few days ago and is now available for everyone signing up for the beta program for software.
As before, if you are in the beta program then the iOS 9.2 beta 1 will be offered to you as an over-the-air update on your iPhone device, iPod touch and iPad device. There is no option to turn back to the previous versions once you get your iPhone updated to the iOS 9.2.
Also, if you check for change from the previous software versions this new build makes it possible to enable the user-installed extensions of Safari. This feature is also available when your web browser is working in the third-party applications.
Obviously, there are some bug fixes that need to be done soon. The final version of the iOS 9.1 was sent out in the public last week only and we should expect it to get released before iOS 9.2 is finished.
