The most recent 3DS system update provides free access to all of Boingo's North American airport Wi-Fi hotspots, which means layovers just got another dimension of fun. Boingo operates the Wi-Fi in 42 airports in North America and suggested that free connection for the 3DS would keep bratty kids quiet while waiting for their flights -- at least, that's what we got out of this quote from Boingo: "With the holiday season approaching, more leisure travelers and families with children will fill our airports and have access to our hotspots."
