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.
Java applications may attempt to, for example, establish a
data connection or send a message. To edit the
permissions of an installed Java application and define
which access point the application will use, select
Installed apps. , scroll to the application, and select Open .
After you install applications to a compatible memory
card, installation files (.sis) remain in the device memory.
The files may use large amounts of memory and prevent
you from storing other files. To maintain sufficient
memory, use Nokia PC Suite to back up installation files to
a compatible PC, then use the file manager to remove the
installation files from the device memory. See “File
manager” , p. 70 . If the .sis file is a message attachment,
delete the message from the Messaging inbox.
