If you plan to use BES to deploy applications to BlackBerry devices, you must make sure of the following before you install the offline client on the BlackBerry device:
The RIM BES software is installed and configured correctly, using RIM’s installation documentation. The installation directory is referred to as %RIM% in this guide.
The RIM BlackBerry Desktop Manager software is installed and configured correctly. Unwired Accelerator’s minimum requirement for the BlackBerry Desktop Manager software is version 3.6 SP3a.
The BlackBerry device has connectivity with BES that you can synchronize between BES and the BlackBerry device.
