From the PDF instructions, it looks like it strengthens the connection between the Shuttle and the External Tank. I have an early edition of this set and will call for the service pack tomorrow.
edited to add the following:
Just called LEGO and they said there wouldn't be a problem to send out the service pack. The rep who assisted me confirmed that the pack is to keep the set stable for people who are more likely to play with their sets, but that the existing set, when displayed as a static model, will be fine and won't fall apart.
So, those of you with budding little LEGO maniacs might want to call for this service pack.
My daughter loves airplanes and the space shuttle, and is demanding that I build my set soon.
