Authority certificates
To use some WAP services, such as banking services, you need an authority certificate.
Using the certificate can help you to improve the security of connections between
your phone and a WAP server.
You can download the certificate from a WAP page if the WAP service supports the
use of authority certificates. After the download, you can view the certificate, then
save or delete it. If you save the certificate, it is added to the list of certificates in
the phone. Your phone alerts you if the identity of the WAP server or WAP gateway
cannot be verified or is not authentic.
To view the list of authority certificates, select Menu > Services > Settings >
Certificates > Authority certificates > Certificate list.
