JQuery Mobile Device Scaling

I am using JQuery Mobile and I am having trouble with the scaling from my browser to my iPhone.

When I load it on a browser (safari) it shrinks and expands just fine. However when I load it on my iPhone it doesn't scale. It allows you to scroll left and right when it shouldn't.

Is there something I am supposed to add to make it scale down on recognize that it's a mobile device.

Here is my current html.

    <head>
        <title>Page Title</title>
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="stylesheet" href="http://www.domain.com/css/jquery.mobile-1.0b1.min.css" />
        <link rel="stylesheet" href="http://www.domain.com/css/base.css" />
        <script type="text/javascript" src="http://code.jquery.com/jquery-1.6.1.min.js">

        </script>
        <script type="text/javascript" src="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js"></script>
    </head>

    <body>

        <body>
            <!-- Start of first page -->
            <div data-role="page">
                <div data-role="header">
