iPhone users are being urged to update their devices to the latest iOS software, or risk not being able to use their phones in the future.
That's because an older version of iOS is set to lose some must-have features including access Maps, for making their way around their town or country, Siri, to access their phone using audio, the App Store, for vital applications and more.
The upcoming change appears to be focusing on iPhones still using iOS 11 to iOS 11.2.6 with owners no longer being able to use critical software.
