Has anyone tested autofocus on WordPress 3.0?

I am using WordPress 2.9 to test this theme in a sandbox at https://www.atleastzero.com/sandbox but I was wondering if anyone has used this theme on the new WordPress 3.0.

I may try upgrading to WordPress 3.0 later, since I have this blog set up in a testing environment, but was wondering if anyone else has already done it. I will post back with my results.
