Apple, today released the first of its beta versions of its iOS 9.2 for the Public. The build version of the update went initially to developers and was later released to Apple Users who signed up for the Beta programme.
If as Apple users, you are signed up for the beta program iOS 9.2 beta 1, the over-the-air updates will be offered to users on their iPhone, iPad, or iPod touch. However, Users will be unable to restore the new updates and turn back to the older versions. This is not possible once you agree to update to iOS 9.2.
A new feature as part of the iOS 9.2 beta update is the fact that it's now possible to enable user-installed extensions for Safari while the Web browser works on third-party apps. Its expected that some new updates will fix this issue.
The iOS 9.1 was released only last week, so its time until Apple will release a stable version of the iOS 9.2. Till then only Beta versions will keep rolling in.
