Apple have released their latest iOS update for the iPhone, iPad & iPod Touch.
iOS version 8.2 brings a range of big fixes, and software updates, and is recommended for all users.
No reports yet of major bugs, which is reassuring given Apple's recent track record in releasing updates that break more then they fix.
You'll find a new App installed, which gives support for the yet-to-be-released Apple Watch. This app will allow connectivity and data transfer between the Apple Watch and the iOS Device.
You can install the update NOW, by simply going to Settings - General - Software update on your iOS Device.
