Pushing the BlackBerry Device Software and the BlackBerry Desktop Software to users' computers
You can use third-party applications to create a single upgrade file that contains the BlackBerry® Desktop Software and the BlackBerry® Device Software, and send the upgrade file to the computers of your BlackBerry device users. The application loader tool on the computers upgrades the BlackBerry Device Software on the BlackBerry device.
The upgrade file installs the BlackBerry Desktop Software and the BlackBerry Device Software on the computers of your BlackBerry device users. To upgrade the BlackBerry Device Software on their BlackBerry devices, users can connect their BlackBerry devices to their computers and start the BlackBerry® Desktop Manager.
This upgrade process applies when you upgrade from BlackBerry Device Software Version 3.5 or earlier.
