You can install two types of applications and software to 
your phone:
J2ME

applications cannot be installed on your phone.
Other applications and software suitable for the 
Symbian operating system. The installation files 
have the .sis extension. Only install software 
specifically designed for your phone.
Installation files may be transferred to your phone from a 
compatible computer, downloaded during browsing, or 
sent to you in a multimedia message, as an e-mail 
attachment, or using Bluetooth. You can use Nokia 
Application Installer in Nokia PC Suite to install an 
application to your phone or a memory card.
After you install applications to a compatible memory 
card, installation files (.sis) may remain in the device 
memory. The files may use large amounts of memory and 
prevent you from storing other files. To maintain sufficient 
memory, use Nokia PC Suite to back up installation files to 
a compatible PC, then use the file manager to remove the 
installation files from the device memory. See “PC Suite,” 
p. 81 and “File manager,” p. 92. If the .sis file is a message 
attachment, delete the message from the Messaging 
inbox.
