Signing digital applications
Symbian Signed
“Symbian Signed” is a new program from Symbian that supports tested and digitally signed applica- tions on Symbian OS phones. It is supported by all Symbian licensees including Sony Ericsson.
A “signed” application means that the application has passed the test criteria and is digitally signed to guarantee the source and integrity of the application. Sony Ericsson encourages all users to use signed applications only.
Developers are allowed to use a Symbian logo called “For Symbian OS” to indicate compliance to the pro- gram. For further information see the Symbian Signed white paper.
Installing ”Symbian Signed” applications on the P800, P900 and P910 series
In order to install an application that is “Symbian Signed”, a Symbian root certificate must be present in your phone. This certificate is pre installed in the P900 and P910 series mobile phones but needs to be installed in the P800 series mobile phones by following the installation steps in the section below: “How to install the Symbian certificate”.
How to check if the Symbian certificate is installed
•Go to Applications
•If the Symbian certificate is not there you will need to install it.
•You must have the “Sony Ericsson” certificate in the list. If you do not see the “Sony Ericsson” cer- tificate you must contact Sony Ericsson customer support.
All future Symbian OS based phones will have a preinstalled Symbian root certificate from the factory. If you have accidentally erased it from your phone it is possible to use the same procedure as for the P800 series.
