Oh, Silly Korea, how I "heart" thee.
Koreans are now using processed sausage snacks as a stylus for their iphone. It's a pretty brilliant idea and apparently sales of the sausages have increased 39% when compared to the same sales period a year before.
It's just so Korean to Macgyver a solution like this. I mean now you don't have to take off your gloves to turn off your music, you can just use your sausage. Plus, they don't cost that much (60 cents). And if you get really hungry, you have a solution.
