How to get WAP interface if using Blackberry like crackberry.com forums?
 

I am considering purchase of vBulletin due to it being used for the implemenation of the Crackberry.com forums ( http://forums.crackberry.com/ ). When I go there on my PC I get a version optimized for a larger screen and when I go on my Blackberry I get a version optimized for the smaller screen. What do I have to buy to set somthing like this up for my company?
