The latest beta of iOS 6 came without a YouTube app, which Apple explains was removed because its licensing deal with Google over the app had ended.
Those remaining on iOS 5 will continue to be able to use the older YouTube app. It's still not clear at this point whether or not iOS 5 users will be able to upgrade to the newer YouTube app that's incoming.
So far, Apple's been tight-lipped about giving any new details for the new app. Google and YouTube aren't saying much easier. The only comment that a YouTube spokesperson offered to Engadget regarding the app was the following: ""We are working with Apple to ensure we have the best possible YouTube experience for iOS users."
New details are sure to surface closer to the fall, when iOS 6 is expected to launch.
