Enter license codes on a BlackBerry device by copying the code into the text field that the application displays when launched for the first time. If you did not write down the key, use the BlackBerry App World to view it.
To enter the license key, open the BlackBerry App World application, and navigate to the My World screen. Highlight the application, press the Menu key to the left of the trackpad, and choose View Registration Key. Press Copy when the key shows up, and open the application that the key activates. When the application asks for the key, paste it into the field, and confirm.
