Nokia has launched a free wi-fi trial service across central London, with 26 hotspots available across the capital.

The trial will continue until the end of the year and if deemed a success will rolled out permanently at the start of 2012.

The free wi-fi service is currently concentrated around the West End, with Westminster and Victoria also hosting hotspots. Many of the areas are reportedly based around old phoneboxes owned by Nokia’s partner Spectrum Interactive.
