Check this out: http://www.nokia.com/nokia/0,,47878,00.html It is a Bluetooth adapter from Nokia utilizing the Pop Port on select Nokias. It will add Bluetooth functionality to Nokia phones tha do not have it (such as my brand new 6610). It make the phone slightly longer but I think its better then having a dongle hanging off the phone (like the Jabra or Plantronics adapters). The adapter is powered by the phone battery and is compatible with non-Nokia Bluetooth headsets. The Nokia site states that this device will be available first quarter of 2004. Has anyone tries it out? Any opinions?
