THE OTHER TAB

The other tab contains all settings that are not related to the device or connections. This is also where settings from system components and add-ons, developed by third-party developers, will be found.

Certificate manager

Digital certificates ensure that the Web or WAP pages you visit, or any software you install, really are created by the person you expect.

Certificates may be present on the pages that you view or the software that you download. Your P900 compares these certificates with a set of certificates that are stored in Certificate manager to ensure the authenticity of the page or software. If the certificates do not match, your P900 informs you, and gives you the following choices:

Prevent the page being loaded or the software being installed.

Continue at your own risk.

The certificates on your P900 have been created and issued by an independent organisation that ensures their authenticity.

Security information

Security information is displayed when Certificate manager cannot be sure of the origin of the page or software. For example, security information will be displayed if:

The certificate on a page has expired.

The identity of a software manufacturer cannot be verified.

Security information is also displayed when a certificate on your

P900 has:

Expired.

Been revoked by the independent organisation that issued it.

Adding and deleting certificates

Your P900 handles certificates automatically so, most of the time, you can browse the Internet securely without using Certificate manager. If you do need to add or delete a certificate, you will usually be informed by your network operator or system administrator. You should delete a certificate from Certificate manager if you are informed, or suspect, that:

The certificate does not belong to the person who supplied it.

The certificate was issued incorrectly by the independent organisation that created it.
