The clamping, suction-cuppy-gooseneck thingy pictured below is designed to hold your phone or media player up for display on the plane. It looks like it could function in some other environments as well. But the method used for supporting your device - suction, probably isn't the best approach for compatibility with *all* handsets. Still, it apparently works well with polished surfaces - like the back of an iPhone.
The creators promise compatability "with iPhones, iTouches, iPods, Blackberrys, SmartPhones, and PMPs of various brands." It's definitely better than propping a $400 gadget against a plastic cup half-full of soda. The iFlyz is 5.5 inches long and 2.5 inches wide, and weighs two ounces. It costs $29.99.
