The YouTube app on 3DS can be, by way of a sneaky link, used to access other sites in the app's mobile browser view.
It seems as if the 3DS implementation of YouTube may be variation on the mobile version of the video streaming site, simply enclosed within a browser wrapper. One user managed to poke deeper into the app's settings, unlocking the ability to search Google and view other sites - albeit in mobile view.
In order to do so:
- The top left menu must be opened and a Google+ account logged in.
- Click on Settings in the left menu.
- Click on Email.
- Click on Change on Google+
- Click Download Google Chrome
- At the bottom of the page that follows, click on Google to launch the mobile Google page.
Have you tried out the YouTube browser?
