Superior P910I User Manual

It is possible to install new applications in your P910i. These 
applications can be obtained in several ways, for example:

• from the Internet.
• from  a  CD.
• from a Memory Stick.
• as an email attachment.

There are two types of installation files for applications:

• SIS (Symbian Standard Installation) made for P910i or other 

Sony Ericsson devices.

• MIDP JAR (Mobile Information Device Profile Java 

Archive).

Note SIS and JAR files are installation packages containing one 
or more files.

Programs made for the Sony Ericsson P800 and P900 series can 
also be used in the P910i.

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 possible to install in the P910i. 
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 files in SIS format are typically used for installation 
of Epoc or PersonalJava™ applications or other content into the 
P910i 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 are certain 
of the origin of the SIS file you can take an installation decision 
based on what you know about that vendor. Your P910i supports 
cryptographic verification of vendor identity.

During installation the P910i verifies a digital signature and 
certificate in the SIS file against a root certificate in the phone. 
Successful verification means that you can trust the origin of the 
SIS file and that the content has not been modified after it was
