have been stored in your phone. Move the joystick to the right to see a list of user
certificates, if available.
Glossary: Digital certificates are used to verify the origin of WAP pages and
installed software. However, they can only be trusted if the origin of the certificate
is known to be authentic.
Digital certificates are needed if you:
• want to connect to an online bank or another site or remote server for actions that
involve transferring confidential information, or
• want to minimise the risk of viruses or other malicious software and be sure of the
authenticity of software when downloading and installing software.
Important: Note, however, that even if the use of certificates makes the risks
involved in remote connections and software installation considerably smaller, they
must be used correctly in order to benefit from increased security. The existence of
a certificate does not offer any protection by itself; the certificate manager must
contain correct, authentic, or trusted certificates for increased security to be
available.
