The Blackberry Web Client is now, and has been for a while, called Blackberry Internet Service (BIS). It can be accessed from your provider's website or from the "setup internet email" icon on your BlackBerry. You just type in your email address and password and the BIS will store it and automatically forward your mail right to your phone every 10-15 minutes. As the previous poster stated you'll also be able to send mail right from your Blackberry as if you were sending from your computer. You can have up to 10 email addresses set up this way.
