Query: no NOKIA compatibility

It would have been nice to know that this headset does not work with the Nokia 8860. The information [here] leads one to believe that the Plantronics M175 will work on all phones with a 2.5 mm jack. When I received the headset and could not get it to work, I had to call Plantronics customer Service in order to get the info regarding non-compatibility. It would have been nice to have more information BEFORE I made my purchase.
