You can upgrade the BlackBerry® Device Software over the wireless network, or if you have installed the BlackBerry® Desktop Software on your computer, you can upgrade the BlackBerry Device Software using the application loader tool of the BlackBerry® Desktop Manager. For more information about upgrading using the BlackBerry Desktop Manager, see the BlackBerry Desktop Software Online Help.
When a BlackBerry Device Software upgrade is available for you to download over the wireless network, a Wireless Upgrade icon appears on the Home screen. The available upgrade might be a complete software upgrade or a software update only. If the available upgrade is a complete software upgrade, your BlackBerry device data is backed up and restored over the wireless network during the installation process.
The duration of the upgrade process can range from 15 minutes to 2 hours, depending on the type of upgrade, the amount of device data, and the number of applications on your device. You can use your device when you download the software, but you cannot use your device or make emergency calls when you install the software.
For more information, contact your wireless service provider or administrator.
