For some reason, I don’t think this is an official Apple product, but that doesn’t make it any less fun. Unlike a real iPhone, the iCushion can run only one app. It’s called “squishy” and it helps you get nice and comfortable.
The guys over at Korea’s Early Adopter Shop are offering the iCushion for 19,800 KRW (appx. $17 USD), but good luck trying to get one of these outside of Korea. Maybe you can fly a whole planeload of people over there and have them use these as neck rests on the flight back to the States.
