About updating the BlackBerry Device Software
You might want to update your BlackBerry Device Software to access new applications and features or to resolve a
technical issue. The duration of the update process can range from 15 minutes to 2 hours, depending on the type of
update, the amount of smartphone data, and the number of applications on your BlackBerry smartphone. You can't use
your smartphone or make emergency calls when the update is in progress.
Depending on your wireless service provider or administrator, you can update your BlackBerry Device Software over the
wireless network, from a website, or using the BlackBerry Desktop Software. If you download an update to your smartphone
over the wireless network, extra fees might apply depending on wireless service provider.
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.
