Update the BlackBerry Device Software

You can use your BlackBerry smartphone when you download the BlackBerry Device Software but not while you install the
software. During the installation process, your smartphone might reset or display a white screen. Do not remove the battery
while the update is in progress.
If encryption is turned on, you might need to type your password at various times during the installation process.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you
update any software. Maintaining a current backup file on your computer might allow you to recover smartphone data if
your smartphone is lost, stolen, or corrupted by an unforeseen issue.
