How to update software and install?

Hello,

There are different ways to ensure the highest iOS that your device will support is installed on your device.

This support article has instructions about updating an iPhone or iPad wirelessly --> Update your iPhone or iPad - Apple Support Read the article for recommended criteria for being able to use wireless updating.

You can also use Mac and PC computers to update system software --> Update iOS on iPhone - Apple Support

When updating, your device will update to the highest version currently available that it will support, or it will just say it is up to date (and can't go any higher) and won't install anything. If you want to run a higher system version than your current device is capable of running, you need to buy a newer device.

An iPhone 8 or later will directly update to the latest iOS, 16.4.1

Note that New Rapid Security Responses are delivered only beginning with iOS 16.4.1 ( About Rapid Security Responses for iOS, iPadOS, and macOS - Apple Support )

For a list of equipment supporting iOS 16 and iPadOS 16 (and the current 16.4.1), read this article --> iOS 16 and iPadOS 16 are compatible with these devices - Apple Support

"Software" includes the possibility of apps too:

For apps on a mobile device --> App Store app > Updates, or select your icon in the upper right corner > click update all or scroll down past the first screen to select individual apps.
