Those who are already on iOS 10.3 and 10.3.1 are essentially stuck with the version they have. Apple has now officially stopped signing the previous versions of its mobile operating system, namely iOS 10.
The latest iOS version, iOS 10.3, may be coming out to the public any day now. Apple had suddenly released the seventh beta version of their upcoming new operating system, iOS 10.
Apple is reported to have just very recently started rolling out the iOS 10.3 public beta 2 that will apparently be made available to everyone in a matter of weeks.
The next software update for the iPhone and iPad is expected to introduce a whole new set of features including a cinema mode. The iOS 10.3 is now believed to be on trial period.
