The most expensive iPhone application is called "I Am Rich". It costs 900 USD and available at the iPhone App store. The application doesn't really do anything, except show everyone around that you can afford an application that does nothing for 900 bucks. Luxury, style or showing off - the application has been downloaded 9 times. The application has got a red ruby, which when pressed, makes the screen glitter with gems and crystals - now that's rich.
