I'm curious how would you go about filtering/unfiltering the browser on a blackberry through our BES server. We are using Sonicwall (not sure of the model) all our servers are 2003 as is our Exchange server.
Thanks,

I'm guessing its done using group policy somehow as well as the policy in BES somehow.

Configure an IT Policy to disable the Internet Browser and force all web browsing to occur using the BlackBerry Browser (MDS).

You can then configure the BES to log web browsing traffic if you wish.

Your Sonicwall probably has CFS (content filtering service) as an option which you can subscribe to.
Assuming your BES uses the Sonicwall as its gateway to the Internet, then your handhelds will also, and traffic will be filtered automatically based on the Sonicwall's configuration.
