Has anyone successfully used both WP-Mobile and WP-Supercache?

Basically, the problem is that sometimes supercache will cache a browser version of a page and deliver it to mobile users. Other times, it will cache a mobile version of a page and deliver it to browser users.

The only hints I can find involve putting a string in .htaccess to determine if the user is a mobile and then bypassing the supercache lines. But that doesn't seem to do the entire job.

Help!
