Know what could save you from that inevitable bout of holiday travel-induced rage? Free WiFi on your 3DS, that's what. Let's be real, you and a few million others are about to be stuck waiting on a tarmac somewhere or suffocating in a boarding area throng of weary travelers. So, if you've got Nintendo's latest portable handy, you'll at least have a free internet connection to latch onto, courtesy of Boingo. The company's recently announced an agreement with the Big N to make its service free of charge to users across 42 of our nation's airports. You'll be able to take advantage of the gratis goods once your console receives a scheduled firmware update, due to roll out today. Now if that doesn't get you in a festive spirit, you're probably just a mean, green 'ol Grinch -- or a PSP owner.
