The other day we told you how close the App Store was to reaching the 10 billion mark and now it has happened. 10 billion individual apps have now been downloaded. The lucky 10 billionth person will get a $10,000 iTunes Gift Card. MacPhun is also giving away $5,000 to the same person.

This is a huge milestone for Apple, not to mention a great prize for the lucky winner. I wonder how long it will take for Apple to double this number?
