For everybody's benefits here, I have gathered and summarize all the things that you need to take note for applying the DST2007 patch wirelessly via the Patch Manager:
Caution #1: It is recommended that you deploy the RIM DST 2007 patch manager to
an initial group of 100 users and record the impact upon
system performance. Use that initial deployment as a benchmark to gauge the size of subsequent deployment groups.
Caution #2: It is recommended that you
deploy the RIM DST 2007 patch during off-peak hours but not overnight.
Caution #3: Allow your BlackBerry devices to download third party applications and
access external servers for at least 24 hours after the last group of BlackBerry devices is configured to receive the RIM DST 2007 patch. (

DST2007 Patch Manager can be downloaded here:-
http://www.blackberry.com/DST2007/patch/
Note: Look for "
If you are an IT Administrator and would like to wirelessly push this patch to your BlackBerry users..."
Additional Information:
1. Once the upgrade files have been installed on a BlackBerry device, it must be reset before the changes take effect. This reset could take 15 to 30 minutes to complete. (
Source: KB12258 - BlackBerry device user is prompted to restart after installing the 2007 DST upgrade)
2. If the RIM DST 2007 patch manager download the update file after into
User Mode, allowing the BlackBerry to download the patch manually Options > 2007 DST Patch.
3. RIM is providing an application called
DST2007Query.exe that is designed to let IT administrators verify that all BlackBerry devices have been updated. The application will send a query to the Configuration database and report how many devices have and have not been updated.
4. If the device is reporting "2007 DST patch applied", trust the device. I was informed that the
DST2007Query.exe is not reporting as it should be as devices may not be able to acknowledge over-the-air back to the BES that the patch has successfully been applied.
On how to use the
DST2007Query.exe tool see :
KB12333 - Using the DST2007Query.exe tool .
