Take some balloons, an iPhone 4, and a length of kite string, and you have the makings a bonafide viral hit. These guys strapped an iPhone 4 into a group of balloons, and sent them skyward. They were smart enough to hold on to it, at least, via a kite string.
I must admit, it would have been kind of cool if they had just let it fly away, and then used “Find My iPhone” to figure out where it landed.
