Installing applications

It is possible to install new applications in your P800. These
applications can be obtained in several ways, for example:
• from the Internet.
• from a CD.
• from a Memory Stick Duo.
• as an e-mail attachment.
• from other devices.
There are two types of installation files for applications:
• SIS (Symbian Standard Installation) made for P800 or other
Sony Ericsson devices.
• MIDP JAR (Mobile Information Device Profile Java
Archive).
Note SIS and JAR files are installation packages containing one
or several files.
This chapter also applies to other types of software to install, for
example, system components and add-ons.

Applications from developers outside Sony Ericsson, so called
third-party developers, might be installed in the P800.
Applications which are not approved by Sony Ericsson are not
guaranteed to work correctly or securely, and users install them
at their own risk. Product failures caused by applications not
approved or made for Sony Ericsson will not be covered by your
warranty.

Installation file security
Installation files in SIS format are typically used for installation
of Epoc or PersonalJava ™ applications or other content into the
P800 file system.The vendor who prepared the SIS file decides
where in the file system the various content of the SIS file will
be installed. This means that you need to decide if you trust that
the SIS file does not contain harmful content. If you know for
sure who produced the SIS file then you can take an installation
decision based on what you know about that vendor. Your P800
supports cryptographic verification of vendor identity.
