"As of today, nearly 10 billion apps have been downloaded from the App Store worldwide. Which is almost as amazing as the apps themselves," Apple said on its website Friday. "So we want to say thanks. Download the 10 billionth app, and you could win a US $10,000 iTunes Gift Card. Just visit the App Store, and download what could be your best app yet."
Don't have an iPhone? Fear not, you don't have to buy an app to win the grand prize (though why you'd want $10,000 in iTunes credits if you don't have an iPhone is beyond me, unless you're just that into music). You can simply fill out a form to win. However, to win the contest that way will take some razor sharp timing--only a form filed immediately after the 9,999,999,999th app is sold can win.
Apple's App Store has some 300,000 apps in its inventory. That's significantly more than its main competitor, the Google Android Marketplace, which has about 100,000 apps (although, to be fair, Apple's store has been around longer).
