Nearly 50 billion apps have been downloaded worldwide from the App Store, and the person who downloads the 50 billionth app will get lucky.

Download the 50 billionth app, and you could win a $10,000 App Store gift card. If you download one of the first 50 apps after that,  you may win a $500 App Store gift card.

For those users who want to enter the contest without purchasing an app, Apple has an alternate entry form as well.
