You’ll be able to update right from your device without ever opening i Tunes.Welcome to our i OS updating guide, in which we explain how to download and install the latest publicly available version of i OS on your i Phone and i Pad.
This article will show you how to proceed if your i Pod Touch, i Pad or i Phone is not detected or not recognized.
The easiest way for most people to download i OS 10.3.2 is over-the-air, directly on their device. If you have limited space on your device or software update isn't working for whatever reason, you can update using i Tunes.
You no longer have to use Apple’s i Tunes software to update to a new version of Apple’s i OS operating system, either.
Just open the Settings app on your device, select the General category, and tap Software Update.
At time of writing that's i OS 10.3.2; if you want to update to i OS 11 (which should be announced on Monday night at WWDC 2017), you'll need to install the beta version instead.
