To check certificate details, scroll to a certificate and select Options→ Certificate details.
When you open certificate details, Certificate management checks the validity of the
certificate and one of the following notes may appear:
• Certificate not trusted - You have not set any application to use the certificate. For
more information, see the next section ‘
Changing the trust settings of an authority
certificate’.
• Expired certificate - The period of validity has ended for the selected certificate.
• Certificate not valid yet - The period of validity has not yet begun for the selected
certificate.
• Certificate corrupted - The certificate cannot be used. Contact the certificate issuer.
Important: 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.
Changing the trust settings of an authority certificate
• Scroll to an authority certificate and select Options→ Trust settings. Depending on the

example:
Services / Yes - the certificate is able to certify sites.
Application manager / Yes - the certificate is able to certify the origin of new software.
Internet / Yes - the certificate is able to certify e-mail and imaging servers.
Important: Before changing these settings, you must make sure that you really
trust the owner of the certificate and that the certificate really belongs to the
listed owner.
