Tools and applications

Important: Only install applications from sources that offer adequate

protection against viruses and other harmful software.

To increase protection, the application installation system uses digital signatures

and certificates for applications. Do not install the application if App. manager

gives a security warning during installation.

Important: If you install an application that contains an update or repair

to an existing application, you can only restore the original application if

you have the original application or a full backup copy of the removed

application. To restore the original application, first remove the updated

or repaired application and then install again from the original application

or the backup copy.

During installation, the phone checks the integrity of the application to be installed.

The phone shows information about the checks being carried out, and you are given

options on whether to continue or cancel the installation. Once the phone has

checked the integrity of the application, it is installed on your phone.

INSTALL APPLICATIONS

Open App. manager, scroll to the application, and select Options > Install to start

the installation.

You can also search the phone memory or the memory card, select the application,

and press the joystick to start the installation.

Some applications may give the option of partial installation, allowing you to

select the particular components of an application that you want to install.

If you are installing an application without a digital signature or a certificate, the

phone warns you of the risks. Continue installation only if you are absolutely sure

of the origin and contents of the application.

INSTALL JAVA™ APPLICATIONS

The .JAR file is required for installation. If it is missing, the phone may ask you to

download it. If there is no access point defined for App. manager, you will be asked

to select one. When you are downloading the .JAR file, you may need to enter a

user name and password to access the server. You obtain these from the supplier

or manufacturer of the application.

• To start a data connection and to view extra information about the application,

scroll to it and select Options > Go to web address.

• To start a data connection and check if there is an update available for the

application, scroll to it and select Options > Update.

JAVA SETTINGS

To change the security settings that determine the actions that a Java application

is permitted to do, select Options > Settings. Not all Java applications permit you

to change the security settings.
