Your Bluetooth could land you into a lot of problems if left unattended. While a Bluetooth offers a number of interesting features that can simplify our daily lives, savvy blue jackers are always on the look out.

"It is not only dangerous to leave your Bluetooth on, but it can cost you your phone," said Anail Sharmal of Simba Telecom Ltd.

Sharma says blue jacking allows phone users to obtained data from someone else's phone at times without their consent. One does not have to be a techie to go into your phone using Bluetooth.

Blue jackers with an entrepreneurial mind can send business cards anonymously using the wireless technology., but is does not entail the removal or modification of any data from the device. These business cards often have a clever or flirtatious message rather than the typical name and phone number.

Blue jackers often look for the receiving phone to ping or the user to react. They then send another, more personal message to that device. Once again, in order to carry out a blue jacking, the sending and receiving devices must be within range of each other, which is typically 10 metres for most mobile devices.

Nokia customer care manager East Africa Nicholas Maina warns that the most predominant problem of leaving Bluetooth was the risk of contacting a virus.

The viruses unique to cell phones entrench themselves into the system hence interfere with functionality of the phone. Others may send music videos, funny clips as well as corky messages. "Most people are curious to accept the messages, yet they are not sure who the sender is.

The minute one accepts information in the phone, it is an irreversible act, therefore if it is damaging, it will be already too late," said Maina. The only caution is to switch off Bluetooth when not in use. Hackers can view one phone book as well as lift numbers and other information without the recipient's knowledge but security upgrades over the past few years now make that much more difficult.

Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a short-range radio frequency.
