Bold in blue

Add a new technology buzzword to your vocabulary: bluejacking. The term refers to a new type of junk message, sent as a text alert on PDAs and cell phones.

Bluejacking happens when people walking through a heavily populated area discover they've received an obnoxious message from an unknown sender. Unlike spam, the text is usually a personal note, not an ad.

Messages range from "Hi, you've been bluejack'd" to "I like your dress" to something salacious. Senders can also fire off photos. The recipient is left wondering who contacted him unless the bluejacker decides to reveal himself.

The "blue" part of bluejacking refers to Bluetooth, the technology that lets wireless devices communicate over short distances, usually about 30 feet. Different Bluetooth-enabled devices can spot one another and exchange messages.
