Boingo Wireless and Nintendo have teamed up to bring Nintendo 3DS owners free airport WiFi access in 42 airports across the United States, including Chicago O'Hare, New York JFK, and Houston George Bush Intercontinental.

The Nintendo 3DS is already a great travel companion, with its open-source Internet browser and built-in camera, not to mention a catalog of hundreds of addictive games featuring real 3D graphics. This new feature is one of several included in a system update that became available for download yesterday.

"Nintendo 3DS is our most connected device ever, and this agreement will allow people to stay entertained while they're on the go," said Zach Fountain, Nintendo of America's Director of Strategic Partnerships. "Whether it's accessing special offers and content, downloading items from the Nintendo eShop, receiving surprise SpotPass content, or automatically receiving 3D videos from the Nintendo Video service, there have never been more reasons to connect."

Free airport WiFi from Boingo will also include access to Nintendo's SpotPass feature, which allows the system to detect wireless hotspots and download special content from Nintendo, including exclusive promotions, 3D videos, and add-on game content.

Boingo manages wireless access in more than 400,000 locations around the world, including airports, hotel chains, cafes, restaurants, convention centers, and metropolitan hot zones. Their service generally costs $7.95 per 24 hour period in the United States, with monthly unlimited plans starting at $9.95.
