CSS background-position not working in Mobile Safari (iPhone/iPad)

I have an issue with background-position in mobile safari. It works fine on other desktop browsers, but not on iPhone or iPad.

body {
 background-color: #000000;
 background-image: url('images/background_top.png');
 background-repeat: no-repeat;
 background-position: center top;
 overflow: auto;
 padding: 0px;
 margin: 0px;
 font-family: "Arial";
}

#header {
 width: 1030px;
 height: 215px;
 margin-left: auto;
 margin-right: auto;
 margin-top: 85px;
 background-image: url('images/header.png');
}

#main-content {
 width: 1000px;
 height: auto;
 margin-left: auto;
 margin-right: auto;
 padding-left: 15px;
 padding-right: 15px;
 padding-top: 15px;
 padding-bottom: 15px;
 background-image: url('images/content_bg.png');
 background-repeat: repeat-y;
}

#footer {
 width: 100%;
 height: 343px;
 background-image: url('images/background_bottom.png');
 background-position: center;
 background-repeat: no-repeat;
}

Both "background_top.png" and "background_bottom.png" are shifted too far to the left. I've googled around, and as far as I can tell, background-position IS supported in mobile safari. I've also tried every combination of keywords ("top", "center", etc.), px, and %. Any thoughts?

Thanks!

Update: here's the markup in the .html file, which displays the design & layout fine in other browsers: (I also updated the above css)

<html lang="en">
 <head>
  <title>Title</title>
  <link rel="Stylesheet" type="text/css" href="styles.css" />
 </head>
 <body>
  <div id="header"></div>
  <div id="main-content"></div>
  <div id="footer"></div>
 </body>
</html>

Both background images are very wide (~2000px) so as to take up space on any sized browser.

P.S. I know that there's probably a few more efficient CSS shortcuts I could be using, but for now I like having the code organized like I have it for visibility.

The iPhone/Webkit browser cannot center align background images when placed in the body tag. The only way around this is to remove the background image from your body tag and use an additional DIV as a wrapper.

#wrapper {
 background-color: #000000;
 background-image: url('images/background_top.png');
 background-repeat: no-repeat;
 background-position: center top;
 overflow: auto;
}


<html lang="en">
 <head>
  <title>Title</title>
  <link rel="Stylesheet" type="text/css" href="styles.css" />
 </head>
 <body>
  <div id="wrapper">
    <div id="header"></div>
    <div id="main-content"></div>
    <div id="footer"></div>
  </div>
 </body>
</html>
