If you live in the UK and have a new iPhone 3GS you really should check out the new Nearest Tube app from AcrossAir. One of the first augmented reality apps to go live in the iPhone AppStore. Forget boring 2D tube maps! Try this amazing new application that tells Londoners where their nearest tube station is via their iPhones video function.
When you load the app, holding it flat, all 13 lines of the London underground are displayed in coloured arrows. By tilting the phone upwards, you will see the nearest stations: what direction they are in relation to your location, how many kilometres and miles away they are and what tube lines they are on. If you continue to tilt the phone upwards, you will see stations further away, as stacked icons. Only available to Apple iPhone 3GS users.
