Bluetooth accessories and phones should have no compatibility problems theoretically, but in practice there are some cases that a manufacturer's Bluetooth handsfree won't cooperate with a different manufacturer's phone, even though both have the "B" logo on them. Motorola decided to dispell complications arising from Bluetooth incompatibility, and launched a website where one can get assured about compatibility with products of a different manufacturer. The site currently includes only devices sold officially in England, but devices from other countries are expected to be added later. Motorola's site can be accessed by clicking here.
