BlueTooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, a king in Denmark more than 1,000 years ago. Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets. Wireless signals transmitted with Bluetooth cover short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps. that is all what i wanted to convey to you regarding blue tooth, now how it works A Bluetooth device playing the role of the "master" can communicate with up to 7 devices playing the role of the "slave". This network of "group of up to 8 devices" (1 master + 7 slaves) is called a piconet. At any given time, data can be transferred between the master and 1 slave; but the master switches rapidly from slave to slave in a round-robin fashion. (Simultaneous transmission from the master to multiple slaves is possible, but not used much in practice). Either device may switch the master/slave role at any time. Bluetooth specification allows connecting 2 or more piconets together to form a scatternet, with some devices acting as a bridge by simultaneously playing the master role in one piconet and the slave role in another piconet. These devices have yet to come, though are supposed to appear next year (2007). i hope you got what you want

Look at the Manual,or check the phone Menu for Bluetooth settings.You can connnect a cordless earpiece,play music through external speakers,or send photos from your phone to your computer or a printer or a friend with another Bluetooth phone,all using Bluetooth. Within the settings there should be a "search for devices" option.Turn on the phone's Bluetooth and the device you want to use.if all's working ok,the phone will recognise the device,and they're then linked.

Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, Personal computer, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. it means u can easily transfer data between two bluetooth enabled devices within a short distance.

I have actually heard of the "blue tooth" before...I think that it is where you hook it into your cell phone some way and theres some way that you maybe able to hook it into someone else's phone and get the ringtone that they have on their phone or seomthing like that and then I have also heard that you can hook it into your phone some way and then hook it into your computer and dowload ringtones and be able to put them on your phone for free and I think that you can also hook it into your computer and take the pictures off of your phone and put it on the computer or something like that!
