How do I setup BlackBerry Internet Service on the BlackBerry Pearl 8100?
Scroll the trackball to the Email Settings icon on the home screen and click the trackball. You will automatically be directed to the BlackBerry Internet Service site. You can either provide your existing email address or scroll to “Create New Account”, which will allow you to create an BlackBerry email address. You can also access BlackBerry Internet Service from a PC/laptop by going http://na.blackberry.com/eng/support/blackberry101/setup.jsp#tab_tab_email.
