■ The cache memory
The information or services that you have accessed are temporarily saved in the cache memory of the
phone.
Note: The information or services you have accessed are stored in the cache of your phone. A cache is a
buffer memory, which is used to store data temporarily. If you have tried to access or have accessed
confidential information requiring passwords (for example, your bank account), empty the cache of your
phone after each use.
To empty the cache:
• Press Menu, select Services and then Clear cache.
■ Authority certificates
For using 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
gateway or WAP server, if the Connection security option is set to On.
You can download the certificate from a WAP page if the WAP supports the use of authority
certificates. After the download, you can view the certificate and then save or delete it. If you save the
certificate, it is added to the list of certificates in the phone.
You can only be sure that a WAP gateway or WAP server is the one it claims to be after its identity has
been checked against the corresponding certificate in the phone.
