Street Art London iphone app

The Street Art London App presented by Street Art London and Geo Street Art guides you to the locations of London’s ephemeral street art using the GPS functionality of the iPhone. I’m assuming there will be a lot of Hackney in there it looks like they update it themselves which might mean it’s out of date quickly – I can see a great opportunity to allow people to add their own images. If anyone has an iphone and £2.99 to spare let us know how it is.
