Enforcing IT policy changes over the wireless network
You can send an IT policy over the wireless network to enforce IT policy rule additions, deletions, or changes immediately on C++ based BlackBerry® devices that are running BlackBerry® Device Software version 2.5 or later and on Java® based BlackBerry devices that are running BlackBerry Device Software version 3.6 or later. When a BlackBerry device receives an IT policy update or a new IT policy, the BlackBerry device and BlackBerry® Desktop Software apply the configuration changes.
The BlackBerry® Enterprise Server must resend the IT policy update over the wireless network to the BlackBerry device to update the BlackBerry device behavior and the BlackBerry Desktop Software. By default, the BlackBerry Enterprise Server is designed to resend the IT policy to the BlackBerry devices that you assigned to that IT policy within a short period of time after you update the IT policy.
You can also resend an IT policy to a specific BlackBerry device manually. You can configure the BlackBerry Enterprise Server to resend IT policies to BlackBerry devices at an interval that you schedule regardless of whether you have changed the IT policies. When the BlackBerry device receives an IT policy update or a new IT policy, the BlackBerry device and the BlackBerry Desktop Software apply the configuration changes.
