If you install applications that require a network
connection, note that the power consumption of your
device may increase when you use these applications.
Installing Symbian software
When you install an update or repair to an application,
you must have the original or a full backup to restore the
application. To restore the original application, remove
the application, and install it again from the original
installation file or the backup copy.
To install software, search the device memory or memory
card for the installation file, select the file, and press the
enter key to start the installation. For example, if you
received the installation file as an e-mail attachment, go
to your mailbox, open the e-mail, select an installation
file, and press the enter key to start the installation.
Use the Application manager to remove software. See
"Application manager," p. 79.
Installing Java™ applications
When you install a signed Java application, the cover
phone must be switched on and you must have a valid
SIM card inserted.
1. Search the device memory or memory card for the
installation file, select the file, and press the enter key
to start the installation. For example, if you received
the installation file as an e-mail attachment, go to
your mailbox, open the e-mail, select an installation
file, and press the enter key to start the installation.

2. Confirm the installation. The .JAR file extension is
required for installation. If it is missing, the device may
ask you to download it. If there is no access point
defined, you will be asked to select one. When you
download the .JAR file, you may need to enter a user
name and password to access the server. You can
obtain these from the application provider.
3. The device informs you when installation is complete.
Tip: When browsing Web pages, you can
download an installation file and install it
immediately. Note, however, that the connection
runs in the background during installation.
