Doing a reverse cell phone search
Before you start talking on a Bluetooth cellular phone, you do need to know a few facts. A Bluetooth cellular phone has a range of 30 feet (10 meters), and the devices in question must use compatible versions of Bluetooth. The majority of Bluetooth cellular phones currently in the marketplace works on Bluetooth 1.1. (Two previous versions, 1.0 and 1.0B, were plagued with compatibility issues and have since been discontinued). The Bluetooth Special Interest Group (SIG) reverse cell phone search, a trade association and development group, is releasing newer versions that promise several upgrades and backward compatibility.
