Uninstalling a BlackBerry application involves completely removing a program from your device. Like a computer, a BlackBerry can only hold so much information. Every application on your device takes up space on its storage drive. Uninstalling a BlackBerry application makes room for more applications or content like pictures and videos.
Turn on your BlackBerry.
Select the "Options" icon from your BlackBerry's main menu. From the menu of options that appears on screen, select "Applications."
Highlight the name in the "Applications" menu of the application you would like to uninstall and select the "Menu" button on your BlackBerry.
Choose "Properties" from the menu on screen. Select the "Delete" option. A box appears on your BlackBerry screen requiring you to confirm that you want to remove the selected application from your device. Select "Delete" again to uninstall your BlackBerry application.
