iOS 6 screenshot round up: Maps, Passbook, Tap to Tweet

Apple opened its kimono last night -- giving iOS developers at its WWDC conference a sneak peak at the new features coming in iOS 6.

iOS 6 won't land on iPhones, iPads and iPods til autumn, but screenshots of the OS quickly filtered onto the web. Click through the gallery above to see a roundup of iOS 6 screenshots.

Key features coming in the next gen of the OS include Apple's own Maps offering -- to compete with Google Maps. This includes turn-by-turn navigation, 3D flyovers and data on 100 million businesses.

Apple has licensed mapping data from sat-nav company TomTom which is just as well, since the new Maps app makes TomTom's own iOS app pretty redundant.

Also landing in iOS 6 is Facebook integration -- as Apple finally bakes Zuckerberg's social network into its operating system, as Twitter has been since iOS 5. In the new world order Facebook-loving iDevice owners will only need to sign in to Facebook once and then gain the ability to post and message their Facebook buddies without using the Facebook app.

The Facebook-iOS-6 cake also means Facebook info is pulled onto your phone -- so you'll see Facebook events appearing in your calendar, and the contacts details of your Fb buddies in the contacts app.

Apple hasn't forgotten its first love Twitter, though. Indeed, it's given Twitter pride of place in the notifications tray, where it's adding the ability to tweet or post to Facebook with one tap.

Other new iOS features include Do Not Disturb, which adds the ability to turn off calls and notifications; Passbook, a one-stop-shop for digital tickets, coupons and loyalty cards; and VIP emails, which lets you flag up messages from select people.

Apple has also updated its mouthy voice assistant Siri -- adding sport score smarts and restaurant review info. Siri is also being integrated with cars so you can bark at it while you drive.
