About iOS and iPadOS Upgrades

To check what operating system you have installed, go to Settings > General > About > Software Version. Wikipedia maintains a detailed comparison of iOS devices. The OIT recommends that all iOS and iPadOS devices be upgraded to the most recent version of iOS or iPadOS that your hardware allows for improved performance, security and functionality.

Before installing any iOS upgrade

The OIT provides basic support for current model iOS devices (generally 2 years old or newer) to enable users to connect to the ND wireless network, to access ND Google email and calendaring services, and any central IT service designed for mobile devices. For additional support, please contact your hardware vendor, cell phone carrier, or the provider of the software application.


We strongly recommend running a backup of your device before installing any iOS or iPadOS upgrades to keep your data safe. The OIT recommends utilizing iCloud for iPhone and iPad backups.


  1. Plug your device into power and connect to the internet with Wi-Fi.
  2. Go to Settings > General, then tap Software Update.
  3. If you see two software update options available, choose the one that you want to install.

  4. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now.

For more information on updating your iPhone or iPad, see this guide from Apple here.
