I only read the posting at
http://www.developer.nokia.com/Commu...supl.nokia.com
which says:
"Make sure that your SUPL server is accessible over the internet and then set your server's address in the positioning server's settings. Now the only thing to fix is to make sure that you add your SSL certificate to the phone so that a secure connection can be extablished between the two end-points. That should be all you need."

and there is some handshake logging between "nokia supl server" (I assume that this is supl.nokia.com) and N95 which seems to be about SSL/TLS .

"Nokia Developer Moderator" writes "Nokia has a SUPL server and a PSY that communicates with it over a SSL connection." .

This is information dated 2009 so maybe it is all outdated?
