Apple released the fourth beta version of iOS 6 on Monday, and developers have noted several changes to the upcoming mobile operating system, including the removal of the dedicated YouTube app.

MacRumors reports that Build 10A5376e has arrived three weeks after iOS 6 beta 3, alongside Xcode 4.5 Developer Preview and Apple TV Software Beta 4.

The biggest change in the new beta is that Apple has removed the YouTube app from iOS 6. In a statement about the matter, Apple said: "Our license to include the YouTube app in iOS has ended, customers can use YouTube in the Safari browser and Google is working on a new YouTube app to be on the App Store."

Google also released an official statement, claiming: "We are working with Apple to ensure the best possible YouTube experience for iOS users."

Apple also ditched Google's Map app in iOS 6, instead building its own mapping service from the ground up. Apple's Maps will have a 3D flyover feature and turn-by-turn navigation. Google has already launched a 3D version of its Google Earth, but reports suggest that it is not up to the same standards as Apple's 3D maps.

As well as the removal of the dedicated YouTube app, Apple has added a WiFi Plus Cellular toggle in the Settings menu, which will allow apps to automatically use your mobile network when the WiFi connection is weak.

Apple’s new Passbook app has seen the addition of an App Store button on the welcome screen in iOS 6 beta 4. The report notes that the button is not currently active, but indicates that Apple will use the button to direct users to a dedicated Passbook compatible app section of the App Store.

In the Privacy menu in Settings, Apple has added Bluetooth Sharing to the list.

Some minor bugs have also been fixed in the new build. 

 iOS 6 is set to be released this autumn, probably alongside the iPhone 5, which is expected to launch at a special event on 12 September. The new mobile operating system will bring more than 200 new features to iPhone, iPad and iPod touch, including the introduction of Siri to the iPad, a new Maps app, and more.
