How to update my iPhone 11 to iOS 17?

See instructions in Update your iPhone or iPad - Apple Support

If you cannot update wirelessly, see the following excerpt from that support article:

If the update doesn't appear on your device, use your computer to update your device manually. Learn how to update your device manually if you're using a Mac with macOS Catalina or later, or if you're using a Mac with macOS Mojave or earlier or a Windows PC.

If you are currently running iOS 15 as shown in your equipment profile, you are skipping one version (iOS 16) so may need to use the manual options FoxFifth links.

If your iPhone is too old, it would not be compatible with the newer software updates.

The correct procedure:

• Software Update.
• Update iOS on iPhone.
• If your iPhone won't update.

Good catch, Allan Jones! 👍🏼

I have a question for you:

Would skipping a version cause any potential issues?
