Hi,
When a friend needed to update documents i.e. they had a child a couple of years after they had put in their application and had moved to a different country, they were told to go to the Visa Office in the country where they were currently residing which was London to provide an updated information i.e. birth certificates etc.
As for the jinxed 2007 lot, I concur as I too applied in July 2007 and despite having submitted documents requested in November 2009, still haven't heard since from them since.
Good luck with the application.
