Using just a couple lines of meta you can create a true app look and feel with your mobile site. One plugin I use to get code into the header section is Addfunc Header and Footer Code. This plugin works great because it gives you the option to easily add code on any individual page/post. Be sure to watch the video in this post. Offers a quick look on how the meta line code works.
Use these two lines of code below.
<meta name=”apple-mobile-web-app-capable” content=”yes”>
<meta name=”mobile-web-app-capable” content=”yes”>
