It’s release day for all Apple users among us! iOS 10, watchOS 3, and that other one everybody always forgets, tvOS 10. Since iOS 10 probably matters the most to you:
iOS 10 features a redesigned Lock screen experience with 3D Touch-enabled notifications, a more easily accessible camera, and a widgets screen. A revamped Control Center also offers 3D Touch support along with new controls for music and HomeKit devices. Raise to Wake, a new feature for the latest devices, wakes up the iPhone without bypassing notifications.
Have fun updating.
