Research in Motion has put up an interactive BlackBerry Smartphone User Guide for the BlackBerry Storm.  You will find information about Device Setup, The Basics, Using Your Device, and Advanced Services.  The really cool thing (at first) is that you can actually turn the pages like you would will reading a magazine or a book.  There are standard next and back buttons as well.  The interactive page turning gets old very quickly, but, like I said, is really cool at first.
