Apple has previews iOS 6 which will arrive on iPhone, iPad and iPod touch in autumn.

As expected the firm announced the latest version of its mobile operating system at its worldwide developer conference (WWDC). It comes with over 200 new features, according to Apple, and will be a free upgrade later this year. See also: MacBook Air has Ivy Bridge chip, USB 3.0, 512GB SSD.

Apple iOS 6 for iPhone, iPad and iPod touch

"iOS 6 continues the rapid pace of innovation that is helping Apple reinvent the phone and create the iPad category, delivering the best mobile experience available on any device," said Scott Forstall, Apple's senior vice president of iOS Software.

Apple has ditched Google Maps in favour of its own Maps app with vector-based elements for smoothness. It also offers turn-by-turn navigation with real-time traffic information, 3D views and local search.

"We can’t wait for hundreds of millions of iOS users to experience the incredible new features in iOS 6 including the new Maps app, expanded Siri support, deep Facebook integration, Shared Photo Streams and the innovative new Passbook app." added Forstall.

Another rumour which came true is that Siri will make its way onto the iPad – it was previously exclusive to the iPhone 4S. Siri has new features including the ability to open apps, retrieve sport scores and dictate posts to Facebook and Twitter. It also has an 'eyes-free' meaning the iPhone can be controlled purely by voice.

Integration with Facebook has been ramped up and is "the best ever in a mobile device", according to the firm. Users can sign in and post from Notification Center, Siri and Facebook-enabled apps, including Photos, Safari and Maps.

"You can also “Like” content directly from the App Store and iTunes and see what your friends recommend." said Apple.

Other changes include the ability to use FaceTime over cellular networks, a VIP mailbox, enhancements to Safari, a Do Not Disturb setting and a Passbook app.
