UPDATE: Please use the http://wordpress.org/extend/plugins/wordpress-mobile-pack/ plugin instead, here's a brief description of the new plugin:

The dotMobi WordPress Mobile Pack is a complete toolkit to help mobilize your WordPress site and blog.

It includes a mobile switcher to select themes based on the type of user that is visiting the site, a selection of mobile themes, extra widgets, device adaptation and a mobile administration panel to allow users to edit the site or write new posts when out and about.
