Users of Apple’s iPhone 5 who haven’t updated to the latest available software update are being warned to do so before November 3, 2019, or risk losing access to the App Store, iCloud, email, web, and other essential features.
Those who don’t update their phones by the end of the deadline will need to manually back up and restore their iPhones using a PC or a Mac to update as over-the-air update and iCloud backups will stop being functional.
To update with an iPhone 5, users should go to Settings > Software Update to download and install iOS 10.3.4 on the device.
