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
P908 has:
• Expired.
• Been revoked by the independent organisation that issued it.
Adding and deleting certificates
Your P908 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.
Type of certificate
The type can be either User or Certificate Authority .
• User certificates contain your identity. This type of certificate
is used when the server asks for client authentication. The
client application requests you to identify yourself by
choosing a user certificate.
• Certificate Authority certificates contain server details. This
type of certificate is handled by your P908 when the server
only requires server authentication. This means that your
identity remains anonymous.
Flip removed
This dialogue lets you enable the use of the Virtual flip when the
flip of your P908 has been removed, see ‘Virtual flip’ on
page 17.
Format disk
This dialogue primarily lets you rename and format any
Memory Stick Duo that you install in your P908. Your P908
comes with one Memory Stick Duo.
When you format a disk, you delete all the information on it,
including any applications that you may have installed. You also
delete all information placed on it by other devices (these
folders are hidden except in File Manager).
