Research In Motion's online store for downloading free and paid BlackBerry applications from third-party developers. Launched in 2009 in response to the huge success of Apple's App Store that opened in 2008, App World software is downloaded directly to the user's phone, not via the computer. Users make purchases via PayPal, a credit card or through participating cellular carriers. For more information, visit www.blackberry.com/appworld. See online app store.
