Certificates
Important: 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.
Certificates have a restricted lifetime. If Expired certificate or Certificate not
valid yet is shown even if the certificate should be valid, check that the current
date and time in your phone are correct.
Before changing any certificate settings, you must make sure that you really
trust the owner of the certificate and that the certificate really belongs to the
listed owner.
There are three kinds of certificates: server certificates, authority certificates,
and user certificates. You may receive these certificates from your service
provider. Authority certificates and user certificates may also be saved in the
security module by the service provider.
To view the list of the authority or user certificates downloaded into your phone,
select Menu > Settings > Security > Authority certificates or User certificates.

The security icon does not indicate that the data transmission between the gateway and

provider secures the data transmission between the gateway and the content server.
