@xes, please see above @freemangordon I did some more (intensive) tests (during lunch time/walk under clear sky). And I am sure N9 and google's supl do like it each other. Rebooted, no data connection, no fix within 30 seconds. Rebooted, GPRS data connection, got fix within a few seconds, And to be on the safe side: Rebooted again, no data connection, again no fix within 30 seconds.
