Although you may not be aware of it, the majority of mobile phones these days are actually Bluetooth phones. However, you may be wondering what Bluetooth is and what, if anything, it has to do with you. Bluetooth allows compatible devices to share both voice and data communications through an ultra low power radio signal within a range of about thirty feet. The technology is not limited to simply voice and data exchange. A couple other features may just have you looking at your cell phone in a completely new way - features that allow you hands-free and wire-free connection.
