Install an application
The .jar file is required for installing Java applications. If it
is missing, the device may ask you to download it.

installing an application without a digital signature or
certification, the device displays a warning. Continue
installation only if you are sure of the origins and

Java applications may attempt to, for example, establish a
data connection or send a message. To edit the permissions
of an installed Java application and define which access
point the application will use, select Installed apps., scroll
to the application, and select Open.
After you install applications to a compatible memory
card, installation files (.sis, .sisx) 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 "File
manager", p. 68. If the .sis file is a message attachment,
delete the message from the Messaging inbox.
