Question

　　The group of tourists walking through Stockholm's old street never knew what hit them. As they admired Swedish art works in a storefront window, one of their mobile phones chirped（唧唧叫）with an anonymous（匿名）note:“Try the blue sweaters. They keep you warm in the winter.”

　　The tourist had just been“bluejacked”--secretly sent a text message using short-range wireless technology called Bluetooth.

　　The more people get Bluetooth-enabled mobile phones--both sender and receiver need them for this to work--the more there is likely to be mischievous（恶作剧的）messaging.

　　Websites are already offering tips on bluejacking, and collections of astonished reactions quickly turn up on the Internet. One site, www. bluejackq. com, was set up by a British teenager.

　　“I bluejacked three or four people, ”says 13-year-old Ellie in UK, who runs the site and makes bluejacking a daily affair. Bluetooth has a range of about nine metres. Ellie used it to send a note to a man in a cafe asking how his coffee was and saying that she liked his wife's glasses.

　　Ellie says he looked here and there to try to figure out where the message came from, even sending text messages back and forth with his wife, but to_no_avail.

　　Bluetooth is fast becoming more common on new mobile phones, though Forrester Research says at present only 9 percent of phones in Europe have such a function.

　　The technology is handy for people wanting to use wireless headsets with their phones or for sending data by phone to Bluetooth-enabled printers.

　　When Bluetooth is activated（激活）, it seeks out other equipped mobile phones by itself and sets up a link. Bluetooth phones can be set to block anonymous messaging, but people who carry them don't necessarily know that.
