Certificate management
A list of authority certificates that have been stored in your phone is 
displayed in 
Certificate management
. To see a list of personal 
certificates if available, scroll right.
Digital certificates should be used if you want to connect to an online 
bank or another site or remote server for actions that involve 
transferring confidential information. They should also be used if you 
want to reduce the risk of viruses or other malicious software and be 
sure of the authenticity of software when downloading and installing 
software.
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 device 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.
View certificate details and check authenticity
You can only be sure of the correct identity of a server when the 
signature and the period of validity of a server certificate have been 
checked.
The phone notifies you if the identity of the server is not authentic or if 
you do not have the correct security certificate in your phone.
To check certificate details, scroll to a certificate, and select 
Options
