I don't know what you mean, the code for the social icons is exactly as I gave above. If you need the original code it's also given here:http://www.shape5.com/demo/curb_appeal/index.php/tutorials-menu-48/custom-code-for-this-design
All you do is enter your own url in the href section.
If you need a different icon that would be custom coding. I would recommend editing editor.css and search for "facebook", that will take you to the area of the css that controls these icons. Just make a copy of one of the icons and change the class name.
