When a new version of iOS arrives, the quickest, easiest way to update on-device and over-the-air (OTA) using the Software Update built into Settings app on your iPhone, iPad, or iPod touch. You need to be on Wi-Fi, be plugged in or have more than half your battery life remaining, and you need sufficient storage space left on your device to download the update, but if all those things are true, you'll be up and running the new version of iOS as fast the internet allows. If you have any problems or just want to do it old-school style, you can also update to iOS using iTunes.
