We have submitted updates to both Unofficial iJustine (v1.3) and Unofficial Shane Dawson (v1.1).
These updates allow you to perform standard YouTube community features using your YouTube account. Once they are approved to the store, you will be able to rate videos, subscribe to channels, add videos to your favorites, and view, post, and reply to comments on videos, all right from our app!
We are very excited for these updates to hit the app store and end up in your hands… check back here through the week and/or watch the “more apps” tab in our apps for these new versions to appear.
