Bluejacking is the art of sending a message to a nearby stranger's Bluetooth phone, having first encoded the message as the "Name" field of an address-book entry, i.e., "Name: I have bluejacked you, I 0wn l0l0l0l0l." BluejackQ is a new community site for posting bluejacking experiences.
Ellie and I were just outside a shopping centre in town and she was searching for a victim near where we were sitting. She came up with a contact; some Nokia, I'm not sure which one. We found out a few minutes later that our victim (who showed an un-canny resemblance to Alan Ford) was sitting in Starbucks with his wife.
After they'd left Starbucks, we followed the couple all over town for about 30mins. He couldn't understand what was happening to him and was looking around all over the place for his bluejacker! We went up and down, around in circles, dodging his stare; quite literally, up in lifts, down on escalators!
