We have seen lots of different ways Nokia have been promoting Lumia 800 Windows Phone devices from the past. The latest one seems to be really cool. Nokia Germany as part of its promotion campaign for Lumia 800 have made this arrangement where a Lumia 800 was placed inside a huge block of ice and the passers were instructed that if they take the device out of the ice block, they can get a free Nokia Lumia 800 device ! !
If you remember, we have seen similar marketing concept was done by Microsoft France in the past to promote Windows Phone. You can watch the video of that event here.
