Visit the apple web site at the moment and you’ll be presented with a running counter of app store downloads for the iPhone and iPod touch. Even if it is an American billion it’s still an impressive number.

Apple are looking to mark the occasion of the billionth (is that a word?) download with a $10,000 iTunes giveaway and some hardware. To enter the competition just download something from the app store. Or fill in the “no purchase necessary” form if you’re a cheapskate like us.
