A Google search of "mobilize website" often produced a few leading tools: MoFuse, Mobify and Mippin. MoFuse did not have a free permanent version, so I focused on the other two. I briefly test drove each and found the following:
Mobify: I found this to be the most complicated, but this also means that Mobify is the most customizable. Upon signing in, users are greeted with a CSS editor with a live preview, and content can be managed as blocks. You can set up various templates, as well as preview different sized mobile screens. Once live, you have a customized web address that ended in mobify.me. If you're on a mobile device now, check out chanatown.mobify.me, though be warned, I have not made any significant edits to the format/style for close to a month.
See the mobile version using Mippin here. On one hand, Mippin does a great job of stripping down to the main content (the posts). On the other hand, a downside is that the tool only shows a limited number of posts, and archives are not searchable.
For those on other platforms (Wordpress does have an automatically enabled mobile site feature), I recommend checking out 1) Mippin if you want a simple solution, 2) Mobify if you are interested in being able to customize and are comfortable with CSS editors, or 3) Instant Mobilizer for an all-in-one solution for your website.
