Adding Apple touch icons to your Drupal 7 theme

What is an apple touch icon? It's basically the same thing as the good old favicon.ico. Only it is specifically targeted for Apples iOS devices. This is how you add touch icons to your drupal 7 theme.

An Apple touch icon is the image being used when someone bookmarks a page or adds it to their homescreen. The most prominent exposure I get to touch icons is when I'm opening a new window or tab on my iphone, then I'm usually presented with a neat looking collection of icons from the web sites I frequent often.
