Sending an IT policy over the wireless network
If your organization's environment includes C++ based BlackBerry devices that are running BlackBerry Device Software version 2.5 or later or Java based devices that are running BlackBerry Device Software version 3.6 or later, the BlackBerry Enterprise Server can send changes to IT policies to a device over the wireless network automatically. When the device receives an updated IT policy or a new IT policy, the device, BlackBerry Desktop Software, and BlackBerry Web Desktop Manager apply the configuration changes immediately.
By default, the BlackBerry Enterprise Server is designed to resend an IT policy to the device within a short period of time after you update the IT policy using the BlackBerry Administration Service. You can also resend an IT policy to a specific device manually. You can configure the BlackBerry Enterprise Server to resend the IT policy to the device at scheduled intervals regardless of whether you changed the IT policy.
