Taking a cue from Apple's App Store which allows iPhone users to download applications for their smart phones, BlackBerry-maker Research In Motion (RIM) too launched its online store BlackBerry App World yesterday.

BlackBerry users will now be able to download software, screen backgrounds and games free, though some applications will be charged a minimum of $2.99. Payments will be collected through eBay's paypal.

BlackBerry App World is designed to automatically present the relevant applications for a user's specific BlackBerry smart phone model, RIM said in a statement here.
