I have read through both the threads indicated by peterleinchen, again - since I had been following them when this problem first came up shortly after the release of the security update. I can't seem to find anything to indicate why supl.nokia.com doesn't work after the update and one needs to use google instead.

Given a choice I would rather nokia keep tracks on my whereabouts than google. Reason being nokia are most likely too inept to do anything nefarious with the info, whereas google have proven more than once that they do what they say they don't do.
