Apple unveiled the latest iPhones – iPhone 8, iPhone 8 Plus and iPhone X – at an event on September 12, which are powered by the latest iOS 11 software. While the new iPhones managed to steal the spotlight, there was a crucial bit of information that benefits all the iPhone, iPad and iPod Touch owners and not just the buyers of the new iPhones.

Apple released iOS 11 at the company's annual World Wide Developers Conference (WWDC) 2017, San Jose on June 5. While we've discussed in detail what the new software entails, including AR experience, Photo app upgrade, new Messages features, DND, redesigned Control Center and Apple Store and improvements to Siri, Apple apps and much more, we're here for something more substantial.
