Important information for owners of iPhone 5
For iPhone 5, an update is required to resume accurate GPS location and to use functions that rely on correct date and time including App Store, iCloud, email, and web browsing.
If you didn't update your iPhone 5 before November 3, 2019, you need to back up and restore using a Mac or PC in order to update, because over-the-air software updates and iCloud Backup no longer work.
You can quickly determine which version of iOS is running on your iPhone, iPad, or iPod touch by launching the Settings apps. Once open, navigate to General > About and then look for Version. The number next to version will indicate which type of iOS you are using. Please see below for what version you should have for your device.
