Here's the KB article on on the RIM site:

This article is missing some important points...
It also works for BES 4.0 for Domino (not mentioned in the KB). If you have to create the Registry key (my BES is Domino and didn't have it), create a new DWORD Value. The Value Data (Decimal) is measured in MINUTES. Be carefull when modifying this value, the four hour default was there for a reason. I wouldn't suggest going any lower than 60 minutes.
Once you add/edit the registry entry, you need to restart the BlackBerry Policy Service. Again, the KB article doesn't mention this rather important detail.
To monitor activity, turn up the logging of your BlackBerry Policy Service to debug level 5. Then, simply search this log (look for your application name) to see deployment information (successfull or failure).
