■ 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
