Apple announced Tuesday that after a year in existence, its App Store has counted 1.5 billion downloaded applications for the iPhone and iPod Touch.

Some stats:  In April, Apple announced 1 billion apps had been downloaded from its store, after just 9 months of being open. Just three months later, another 500 million apps have been purchased. Apple says there are 65,000 apps available in the store, and 40 million iPhones and iPod Touch devices sold thus far, with new iPhone 3GS owners likely bumping up those download numbers in the last month.
