If you’ve been lamenting the lack of YouTube on your Nintendo 3DS device, the wait is over as the YouTube app is finally available on the 3DS eShop. Ironically though, the video streaming app on the 3DS does not support 3D YouTube clips. The videos are streamed on the top screen and the bottom screen serves as a touchscreen control hub. You can also use the shoulder buttons to navigate, the directional pad to scroll, or the stylus to control everything.
