About adding applications
The BlackBerry App World™ storefront allows you to search for and download applications for your BlackBerry® device. From BlackBerry App World, you can browse featured and top downloaded items, such as games, social networking applications, and productivity applications. You can view applications by category and search by keyword. Using an existing PayPal® account, you can buy and download items over the wireless network to your device. Items that you buy are stored in BlackBerry App World on the My World screen. To download BlackBerry App World, visit www.blackberryappworld.com. Depending on your wireless service provider, BlackBerry App World might not be available.
You can also access new applications through the application center. You can use the application center to add, update, or return to the previous version of a select number of applications that are hosted by your wireless service provider. This might include social networking applications, instant messaging applications, and applications that are specific to your wireless service provider.
Data charges might apply when you add a new application. For more information, contact your wireless service provider.
