This is interesting. The latest beta version of iOS 6, released today, has dropped the YouTube app. Some feel that it may be part of their cutting ties with Google’s applications. For instance, the Maps app has been updated, and no longer features Google maps.
As 9to5Mcc reports, it’s possible that there is some sort of bug or error. However, the app has also been removed from the iPad, and remains on Apple TV.
We will keep you updated if anything else new crops up.
