Nokia 7650 with HDW-2 bluetooth?

[kelvin_ngu]

I saw somebody using nokia HDW-2 bluetooth with his Nokia 7650 other days, so I ask him regarding the compatibility of the bluetooth with 7650 and he told me that he just upgrade his 7650 which included the video camera version and that is. He said the video camera software is originally there after he upgrade his 7650 without any D.I.Y. installation of the video camera software. Is it possible? I don't ask him too much coz I don't know that guy also.

I've heard about a bluetooth hnadsfree for he 7650.. Theoreticall it's not possible but there is a way around.. You have to buy a keychain sized box which plugs into the handsfree port on the top of the cell.... Then you can use a bluetooth headset with the phone. However this increase the size of the phone even more.. As far the built in video MMS installation thingy is concerned i really doubt it..... I've got the latest firmware (4.46) and i had to install video MMS seperately....

is it not possible to write a .sis file as a sort of "driver" for the headset? if not would upgrading to symbian os 7 work and is it possible for the 7650?
