Nokia has setup dedicated London Olympic site on their Nokia Maps page called The road to London:
Path of the Games.
From there you can follow your favorite athletes, see public transportation lines to find the venues in London and schedules. Nokia Maps will of course offer that amazing 3D maps for London.
You will really appreciate our city pagemaps.nokia.com/uk/london, especially if you are a London newbie. The city pages, as you might already know, are available for many locales around the world and actually for all the previous host cities like Athens, Berlin, Paris, Atlanta and Beijing. – Nokia Conversation
CNN will use Nokia Maps on their covering of London Olympics as well.
