Just added a cool background to PhoneArena to make it look a lot better and more Professional and changed the header color to white. The end result looks cool without affecting the functionality at all :D

To change the background, just change the url in the tag

home
{
background-image: url () !important;
}

Just change the URL between the () and done.

Also if you don't want the pic to scroll along with the layout then insert those tags after the above tag
note : the tags should be between the {} brackets of the body tag

background-repeat:repeat !important;
background-attachment:fixed !important;
background-position:center !important;
