In the Safari app, there's an open book-like icon in the top (next to the curvy arrow). That's your saved bookmarks "book."
Touching it opens a pop-up and, if you bookmark is not shown in the first screen, there are two buttons at the top of this pop-up. The on on the right is Edit (which let's you manipulate the bookmarks. The one on the left is to go up in your bookmark hierarchy (should you have built folders).
Hope that helps.
