With just a day to go, Nokia has pushed out another brief teaser, this time pointing towards more map-based contextual functionality. It looks like whatever the company's got up its sleeves, alongside any new Lumia hardware, should include some map-based social network chops and City Lens features -- not much of a shocker given that the latter has just shed its beta status.

Update: Nokia's throw out another video -- which reveals that its good-looking star does manage to find those shoes. Phew. We've added it after the break.
