Trusted certificates

To establish a secure connection when using certain WAP services, for example banking or WAP shopping, you need certificates in your phone.

The different types of certificates are as follows:

•Server certificates are used to identify a WAP gateway to the phone and to show that it is certified by a trusted authority. The server certificate is checked against trusted certificates that are stored in the phone. If the phone cannot verify the identity of a server, you are given the options to terminate or continue the connection.

•Trusted certificates are used to verify the WAP gateway that you are trying to connect to. Your phone may already contain trusted certificates when you buy it.You can also download trusted certificates from Sony Ericsson or other WAP pages.

To check the certificates in your phone

1.Scroll to WAP services, YES, Options, YES, Common, YES, Security, YES, Trusted certif., YES.
