These are the two sites I've seen for downloading new firmware.
ftp://custftp:FQSswyvGQ20So@ftp.ectaco.com/
http://www.jetbook.net/upgrade.php
As of 10PM PST April 2nd. The new firmwares or updates for the ECTACO Jetbook have not been posted, unless there is some other location to find them.
Yet still ... I wait in anticipation.
