■ Install or remove applications
You can install two types of applications to your device:
• J2ME
TM
 applications based on Java
TM
 technology with the extension .jad or .jar. 
PersonalJava
TM
 applications cannot be installed on your device.
• Other applications and software suitable for the Symbian operating system. 
The installation files have the .sis or .sisx extension. Only install software 
specifically designed for your device.
Important: Only install and use applications and other software from trusted 
sources, such as applications that are Symbian Signed or have passed the Java 
Verified
TM
 testing.
Important: Even if the use of certificates makes the risks involved in remote 
connections and software installation considerably smaller, they must be used 
correctly in order to benefit from increased security. The existence of a certificate 
does not offer any protection by itself; the certificate manager must contain correct, 
authentic, or trusted certificates for increased security to be available. Certificates have a 
restricted lifetime. If "Expired certificate" or "Certificate not valid yet" is shown, even if the 
certificate should be valid, check that the current date and time in your device are correct.
Before changing any certificate settings, you must make sure that you really trust the owner 
of the certificate and that the certificate really belongs to the listed owner.
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 by using Bluetooth technology. You can use Nokia
