I'm sure that we can come up with something for those using tiny browsers. I'm not sure of what SBS used for the mobile version, however I've used some other sites, and run one that a minimalistic style/theme for mobile use.
The question is should it focus on getting the content out, or making it pretty with all the frills just mobile? I prefer the first way on a phone, graphics and all that nonsense don't really add anything but load time.
Little problem: It's not actually recognizing one of my phones as a phone, making it try to load the full version of the site and failing miserable.
What phone and browser are you using?
