IPhone users should be prepared to update their device to the latest iOS software, as failing to do so could stop them from being able to use their devices.
Those who keep older versions, particularly iOS 11 to iOS 11.2.6, will loose access to important features, reports the Mirror. These include access to maps, virtual assistant Siri and even the app store, further limiting access to third party programmes.
iPhone models that will be primarily affected range from the iPhone 5 and lower but even the iPhone 7 could see the change if software isn't updated. The change was reported by Twitter user @StellaFudge, who said users will be notified before it comes into affect.
