Install an application
The .jar file is required for installing Java applications. If it is missing, the device may ask you
to download it.
1. To install an application or software package, select Installation files, and scroll to an
installation file. Applications on the memory card are indicated with .
2. Select Options > Install.
Alternatively, search the device memory or the memory card, select the application, and
press the scroll key to start the installation.
During the installation, the device shows information about the progress of the installation.
If you are installing an application without a digital signature or certification, the device
displays a warning. Continue installation only if you are sure of the origins and contents
of the application.
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. 61. If the .sis file is a message attachment, delete the message
from the Messaging inbox.

In the Application manager main view, select Installed apps., scroll to the software package,
and select Options > Uninstall.
