Nokia E71 - Manual (Page 114)

You can install two types of applications and software on your
device:
• Applications and software specifically intended for your
device or compatible with the Symbian operating system.
These software installation files have the extension .sis
or .sisx.
• Java ME™ applications compatible with the Symbian
operating system. The Java application installation file
extensions are .jad or .jar.
Installation files may be transferred to your device from a
compatible computer, downloaded during browsing, or sent
to you in a multimedia message, as an e-mail attachment, or
with Bluetooth.
During the installation, the device checks the integrity of the
package to be installed. The device shows information about
the checks being carried out, and you are given options to
continue or cancel the installation.
If you install applications that require a network connection,
note that the power consumption of your device may
increase when you use these applications.
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 the installation.
