New Nokia owners take notice: Espoo just launched an "exchange program" for certain Nokia-branded chargers. According to the world's largest handset maker:"We have determined that the plastic covers of the affected chargers could come loose and separate, exposing the charger's internal components and potentially posing an electric shock hazard if certain internal components are touched while the charger is plugged into a live socket."The chargers affected are models AC-3E and AC-3U, manufactured between June 15 and August 9, 2009, and model AC-4U, manufactured between April 13 and October 25, 2009. Fortunately, Nokia provides a website that removes all the guesswork from obtaining your free replacement.
