Using your Browser on your BlackBerry, go to http://mobile.blackberry.com, then click on Fun and Games, then Themes. I'll warn you ahead of time that I think their deal with AT&T doesn't allow them to make free themes available - AT&T wants you to pay THEM for the privileged!
A great site for Themes is BlueRoomSolution. I find easier to browse the themes on my computer, then copy and email the OTA (Over The Air) installation links to myself to install them. You have to register on the site to get access to the OTA links.
