The first firmware update for the Nintendo 3DS has gone live for download across the world - it should take around 15 minutes to download.
The update is a rather minor one, as the main feature is that you can download an OK Go music video for "White Knuckles", although it's only viewable in 2D.
The update is also said to improve the "overall wireless connection" to the Nintendo 3DS, which can only be seen as a good thing. There were some ordering changes to the hub icons too, but that's about it.
Update: The video is viewable in 3D.
