What part of your site isn't working on smart phones?
I use a low-end Android (Optimus V) and one of my officers uses a slightly nicer one (Galaxy something), and we both can use every function of our site with no problems at all. I was actually pretty surprised at this, considering I'm using a drop-in template with a few changes. Even the forums scale automagically when I zoom in/out.
I know that there is probably formatting that can be done to help make the sites mobile friendly however I would I don't really care about the looks of a site on a mobile device and personally don't like most sites that are do provide mobile support.
I also hate mobile versions of websites because they usually compromise on the features. As it is right now, using the website from my droid is almost as easy as using it from my computer with all the same functionality.
