I recently brought the above headset from my local computer market & was told that it would also work on my phone, (Nokia 6630) and the wife's (Samsung D500). tried 'search for new devices' with both phones & neither will pick it up. The trader i brought it off said that it is possible to upgrade the firmware in the headset via 'Motorola's Website' (very vague, i know). ive done some searching round various motorola sites & here at aD and can find nothing. Can anyone help?
