Install or remove applications

■
You can install two types of applications to your device:
TM
• J2ME applications based on Java
or .jar. Personal Java
• 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
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.
