when i did Ovi Publish Signing, i have received three files form Ovi Publisher Support : OVI_12-31-2010.crt ; OVI_12-31-2010.key ; and xxxxxx_OviPublishCert_Jan20.sis;
i use "Qt Creator" to develop Qt app, i built myapp.sis file to submit to Ovi Store publishing, i included crt file and key file in Qt release building (under Project : Build Settings), but i don't know where i can put "xxxxxx_OviPublishCert_Jan20.sis"

question : how can i use the sis file that was sent to me by Ovi Publish Signing?
