iOS 10 is available now!
According to Apple, iOS 10 is the “biggest release ever” for iOS devices, with major updates for Messages, Siri, Photos, Maps, Apple Music, Apple Pay, and the iOS interface.
Apple released iOS 10 this morning, the latest operating system designed for the iPad, iPhone, and iPod touch. iOS 10 can be downloaded on the iPhone 5 and later, the iPad mini and later, the iPad 2 and later, and the 6th generation iPod touch. It is recommended for iPhone 5 and 5C owners to hold off downloading as it has proven slow for some beta users.
The update is available on all eligible devices via the Settings app. To access the update, go to Settings -> General -> Software update. It may take a few minutes for the update to show on your device due to high user demand.
