Developing a mobile friendly site

I have a site I am working on at http://phildobbie.com/itnew.

I chose Gavick because I thought the templates could adapt to mobile devices. I have selected the iPhone option of iPhone in the template settings, but it keeps showing the main site.

But I notice I have no mobile.css loaded. Is this where I am going wrong.

What I really want to do is create a separate main menu for mobile users, to present less content and skipping many of the modules.

Can anyone get me started in the right direction?

Maybe it is just your browser cache, I've change user agen to iPhone and this is how I see your site >> http://cl.ly/image/0q1j3s1l3N3o

Aha! It was there all along. Thanks

So the problem is resolved yes ?
