Are you talking about making a bookmark from a web page (to be displayed on your home screen)?
If yes, when you choose to "Add to Home Screen," you should get a pop-up window in which you can name the bookmark. The cursor should already be in it and there should an "x" so you can delete the text that's already there. Name the bookmark what you wish (remember, however, that you are limited on character length) and then hit the blue Add button.
Hope that helps.
