A few days ago RIM announced via tweet that the BlackBerry App World now contains more than 15,000 applications. 15,000 applications might not seem like a lot in comparison to the hundreds of thousands of apps that are found in the Apple App Store and Android shop, but RIM is definitely on their way. Supply and demand is the name of the game and themes are high in demand.  Currently, there are 15,000 related theme items available in the BlackBerry App World. Even tho they are not quite apps, they are still counted anyways.
What are your favorite BlackBerry Apps? What apps would you like to see land at the App World?
