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

TM
 
applications cannot be installed on your device.
Other applications and software suitable for the 
Symbian operating system. The installation files 
have the .sis extension. Only install software 
specifically designed for your device.
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 using Bluetooth. You can use Nokia 
Application Installer in Nokia PC Suite to install an 
application to your device or a memory card.
After you install applications to a compatible memory 
card, installation files (.sis) 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. 87 and "File manager", p. 96. If the .sis file is a message 
attachment, delete the message from the messaging inbox.
