Wild mobile apps

Just spotted an article on TelecomAsia, Tom Hume has also spotted this one. Interesting thing is number 3 ... a ghost detector. Now at Telecom Express and before that at Broadsystem I set up the mobile services for shows such as Most Haunted Live and Ghost Towns Live and I must say I wonder how this actually works. On Most Haunted they walk around with various boxes of electronics checking for temperature and so on. So does this mean you have to plug something into your phone? Anyway its a great arcticle.
