RIM said that it had “recently crossed the 1 billion app download milestone,” and that it is now seeing an average of 3 million downloads per day across the 100 markets where it is now available. The company said that since the store launched two years ago, it has made “many feature improvements, enhanced the look and feel, and added a ton of compelling apps.” It is set to begin a beta of BlackBerry App World 3.0 later this month.

RIM did not state how many apps it has in its store. Earlier this year, among the platform/vendor catalogues, it ranked fourth, after Apple’s App Store, Android Market, and Nokia’s Ovi store. However, it has been reported that developer interest in the platform is cooling, while Microsoft’s WP7 Marketplace certainly seems to have momentum on its side – it has already been forecast that this catalogue will overtake those of RIM and Nokia in the near future.
