In iPhone/iPad you can have the address bar removed by using a meta-tag on your page. However it only works if a user clicks the 'add to home page button'.
For more info iPad WebApp Full Screen in Safari
I need to find a way to slightly change the CSS if the user is viewing the page without the address bar(i.e. accessing the site from homepage.).
padding-top:64px;
Has anyone found a way to deal with this issue?
