You can permanently delete information stored on your BlackBerry in a few quick steps, right from your device. A security wipe saves you from the tedious task of deleting items one by one. You can remove all user added data, such as contacts, email and pictures. You can also choose to remove any applications you’ve installed. Performing a security wipe is a good idea if you’re donating an old BlackBerry or returning one, as it removes all sensitive data.
