Note: If you install software that is not intended specifically for the Nokia
9210/9210i Communicator, its usage can differ significantly from the
usual Nokia 9210/9210i Communicator applications.
You can download or transfer a software package containing the files of the
application into the communicator. Then you can install the application. Software
can also be installed from a memory card. A software package is usually one large
compressed file containing many component files.
IMPORTANT: When downloading or transferring software packages into the
communicator, use only packages whose file names end '.sis'. An
example of a suitable file name is 'MediaPlayer.sis'.
To start the installation, press Install new on the Installed software page. Browse for
the software package you want to install, and press OK. The installation process
begins.
Note: Only install software from sources that offer adequate protection against
viruses and other harmful software. To help you, the software installation
system on the Nokia 9210i Communicator uses digital signatures and
certificates on software packages. See page 222.
If you are installing software without a digital signature or a certificate, the
communicator warns you of the risks of installing software, as shown in figure 93.
Tip: You can also start
the installation by browsing
for the installation package
in communicator memory or
memory card with File
manager, selecting it, and
pressing the Enter key.
