If you add this to the end of your html header / beginning of html body it should hide the title bar on the iphone:
...
<meta name = "viewport" content = "width = device-width, user-scalable=no">
<!-- script um auf dem iPhone die Adresszeile auszublenden-->
<script type="text/javascript" language="javascript">
// Hide MobileSafari Toolbar when page is loaded
window.addEventListener("load", function() { setTimeout(loaded, 100) }, false);
function loaded() {
document.getElementById("topbar").style.visibility = "visible";
window.scrollTo(0, 1); // pan to the bottom, hides the location bar
}
</script>
<!-- ende ausblendskript-->
</head>
<body>
<div id="topbar" width: 300px >
....
cheers
