I am not sure how this mobile thing works. Wouldn't they need UMTS or something similar? Let a mobile phone expert tell you how.....
But the second questions is something you can do quickly. In your template folder open up your style sheet and edit the lines where it reads
Code:
TABLE.header {
background-image: url(../images/header_bg.jpg);
background-repeat: repeat-x;
background-color: #ffffff;
border-right: 1px solid #9a9a9a;
border-left: 1px solid #9a9a9a;
border-bottom: 1px solid #9a9a9a;
}
to read the following
Code:
TABLE.header {
background-repeat: repeat-x;
background-color: #ffffff;
border-right: 1px solid #9a9a9a;
border-left: 1px solid #9a9a9a;
border-bottom: 1px solid #9a9a9a;
}
and the background will be removed.
