Apple has confirmed this saying, “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.” Apple did not, however, explained the reason for kicking YouTube in iOS 6 beta 4 apart from the expired license. So, if you rely on YouTube a lot on your iPhone or iPad, you’ll have to use the web app via Safari for now, or wait for Google’s new YouTube app that Apple says will be made available in the App Store. Google’s YouTube already existed on iOS since the first generation iPhone was released in 2007.
