Nothinig... is just that GAF mobile uses a better and simple layout.... you have a better menu too.
You need to change some setthings in your browser to GAF didn't redirect to the desktop version... it is not automaticly... in Opere I need to say it to indentify like Mobile.
Thanks that's cool to know if I ever want to go to GAF. Which could be never as I don't have a paid email xD.
