It looks like Google Maps isn't the only Google-based app that will disappear when iOS 6 is released in the fall. Engadget readers noticed that the latest iOS 6 beta, which was sent out to developers today, removes the YouTube app from the iOS homescreen when installed.
Both Apple and Google responded to Engadget's inquiry about the app. Apple said the licensing deal it had with Google ended, but "users can still use YouTube via the Safari web app." Apple also said the app would remain on devices running iOS 5 or older, and that Google "is working" on another version.
