As promised, Apple on Tuesday released iOS 10 for its mobile devices. The software update is free and technically compatible with the iPad 4, iPad mini 2, the iPhone 5, the iPod touch sixth-generation, and all subsequent models.
If you have one of these devices, you can update to iOS 10 by navigating to the Settings app > General > Software Update, and it will install automatically. The update is also on our Downloads page, and you can install it manually by plugging your device into a computer with iTunes installed. Obviously if you're jailbroken, you'll want to steer clear of iOS 10.
