According to the official @BlackBerry Twitter account, BlackBerry App World has surpassed 15,000 BlackBerry applications. Seeing how (at the time of this posting) 3835 apps are themes and 3068 apps are Reference & Books, there really are only about 8000 applications, and, even that number is debatable. There are however, well over 15,000 things in BlackBerry App World that can be downloaded, and seeing how long it took to get there compared to the App Store and Android Marketplace, is definitely worth mentioning.
