For BlackBerry setup, you will need to create a forwarding account
using the BlackBerry Internet Service website, which is a service
operated by BlackBerry (Research in Motion Limited.) The exact web
address of the BlackBerry Internet Service depends on your wireless
service provider. To locate the address of your service provider's
BlackBerry Internet Service website, click the link and then select your
wireless provider from the list at the bottom of the page:
http://www.blackberry.com/support/client/index.shtml
You should be able to consult your wireless service provider's
documentation for more information on accessing the BlackBerry Internet
Service website.
For additional information on using the
BlackBerry Internet Service, please visit the BlackBerry Technical
Knowledge Center at the following URL:
