Apple is on a constant mission to always improve on its mobile operating system, iOS, in every version it releases to the masses. iOS 9 will surely be no exception, and upon its release, we can expect the usual talk about debugging technical issues and enhancing system stability. Of course, there will be some new features too. But perhaps the most intriguing thing is that Apple is reportedly working to improve support for older iOS running devices, particularly older models of iPhones and iPads, even those that are not being sold in stores anymore.
