Seems like there really is an app for everything, even ones that adorn your fridge. Just take a look at these iPhone magnets. Once these bad boys become mainstream, they'll knock other magnet competitors right out of the water, just as the iPhone did to other mobiles and smartphones.
Created by Jailbreak Toys, the iPhone magnets are 7/8" square 'apps' that will turn your entire fridge front into a very large, very fun iPhone. Eighteen iPhone magnets costs $12.99, which is definitely a more reasonable price than that of their inspiration.
