Insert code into header.php

Hi,

I have just learned how to create shortcut onto home screens of phones 🙂 and want to replace the icon used to my logo.

I have done this for iPhones ok, following a tutorial, but for Android the tutorial said to insert the following code into the header of each page I want the icon to represent.

<link rel=”apple-touch-icon” href=”/apple-touch-icon.png” />
<link rel=”apple-touch-icon-precomposed” href=”/apple-touch-icon.png” />

So I want it to represent the homepage, so need to insert into the header.php file?

I’d be very grateful if someone could explain HOW I do this, i.e.:

Step 1: Open filezilla?
Step 2: Open X folder
Step 3: download X file
Step 4: Paste the code “Here” etc. etc.

As I don’t want to f-up by doing something really stupid that is obvious to everyone except silly old me:)

Thanks guys.
