Java™
• Security subsystem(s) used (IMPORTANT: see "Security considerations " in the paragraph below): network usage,
time interval if automatic startup is used
• Other information that may be displayed: name of the JAR, parameters, Java™ profile used, URL of the JAR file,
scratchpad size
If you do not wish to download the main data (JAR file), select "Cancel" to refuse to consume more airtime; the JAR file will not
be downloaded. If you accept to install the application, select "OK". The application will be installed.
Before an application is downloaded, the following message may be displayed: "Your handset cannot identify the application.
Please check the source of the application before you install it."
Read the two paragraphs below carefully in order to fully understand the security issues relating to Java™.
WARNING: When you run an application, you may be prompted to grant access to protected features. These features
are protected because their use may cause you to incur costs or expose your personal data. Read the popup security
messages carefully to find out the security subsystem required and to assess whether the application is trying to carry
out a legitimate task. If in doubt, don't hesitate to deny access by selecting the "No" button. The security con-
figuration menu is an advanced feature. You must be fully aware of what you are doing before attempting to
alter an application's security settings. Making inappropriate changes may lead to the application malfunctio-
ning and/or place your personnel data or airtime at greater risk. You are responsible for any changes made to
the security configuration. Under no circumstance can SAGEM SA and/or your network provider be held liable
for any damage resulting from such changes to the security settings. Be aware that depending on your operator's
billing policy, you may be billed for the airtime used when downloading applications.
Security considerations
Java™ is an effective way of offering powerful applications on mobile phones. It allows a mobile phone's integrated features to
be used via applications or games downloaded "over the air" (multimedia playback, network access...).
Your phone is equipped with a sophisticated access control system in order to protect your data and airtime.
The access control system comprises 2 security subsystems:
• Network access (GPRS/GSM communications, HTTP/Web connections...)
• Automatic startup (activation of the application at predefined intervals)
The "Network access" security subsystem has 3 possible authorization levels. These levels are listed from the most restrictive
to the most permissive:
• Never - This authorization level prevents all access to protected features.
• Confirm - The user is prompted to grant access authorization to protected features each time the application is run
• Always - This authorization level automatically grants access to protected features without restriction.
The "Auto. Startup" security subsystem has 2 authorization levels:
• Activate: the application will start up automatically at predefined intervals
• Deactivate: the application will not start up automatically.
Security configuration menu
When an application is installed on the mobile phone, the different "Network access" security authorizations are
displayed and can be selected by the user. The security configuration of the "Network access" subsystem can be
modified via the application's "Settings/Security" menu.
