How to apply theme to Samsung Galaxy S?

Question by Michi: How to apply theme to Samsung Galaxy S?
Hi, my mom asked me to customize her samsung galaxy s after she saw how themed-up my iphone was…
So I downloaded a free theme from the android market place and now I have no idea what to do. I’m not familiar with her phone and neither is she.
How do I apply the theme?
