Now that supl.nokia.com issues are teared down to TLS / certificates flaws inside N900, what about supl.google.com?

My tests with supl-proxy where showing that during (s)UPL sessions with google and sonyericsson much more data was exchanged (compared to nokia and vodafone). With no success at the end.
See my attached log files in post #101 http://talk.maemo.org/showpost.php?p=1369745

Why can't N900 use the data coming from supl.google.com for A-GPS / ACWP?
