How does Zimbra know when to redirect user to the mobile skin?
I am testing the zimbra mobile skin using FireFox user agent switcher. When I switch to iPhone user agent, then go to http://zcsHostName/zimbra, I get the mobile skin as expected. However, when I switch to Blackberry 8830, it tries to load the Advanced version. What do I need to edit/configure for the web app to redirect user to mobile version for Blackberry?

Thanks!
