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

use the file manager to remove the installation files from the
device memory. If the .sis file is a message attachment, delete
the message from the Messaging inbox.
