The mobile e-mail application on the Nokia 6820 enables
you to log in to a private or business e-mail account supporting
POP3, IMAP4, or SMTP protocols.
In addition, the Nokia 6820 messaging device supports BlackBerry
e-mail connectivity. It allows e-mail to come to you, rather
than having to log in to a server and manually fetching it.
BlackBerry is an operator-dependent feature, and requires a
subscription for the service.
