Interesting. Yesterday, I checked the forum on my iPhone, and saw basically the same them as here, but really tiny. This morning, trying to view the forum, I got only .php files, so something was up. Now, on my iPhone, I see a vBulletin mobile theme - not bad, actually. So if you're going to use this mobile theme, you might want to add the Treeleaf logo, and change the colors to match the full theme. But it's certainly more practical this way.
