Depending on your
wireless service provider, you might not be able to change some options for
your personal email account.
You can change options for
each personal email account that you added to your BlackBerry smartphone. You can create email filters, synchronize your
contacts, change your signature or display name, and more.
For more information about personal email accounts, visit
www.blackberry.com/docs/smartphones and click the link
under
Email Setup.
