Default Phone Identification
Being a long served WinMo user i'm quite lost when it comes to Android.

I (and others) have a problem in that the recipient of a phone call via our bluetooth connections to our Nokia CK-7W car kits experience bad echoing.

I have started a thread in the HTC Desire forum and it is clear that I'm not the only one who suffers. Here's the link http://forum.xda-developers.com/showthread.php?t=676175

A user in a WinMo forum posted a solution by changing the Class of Device (COD) in the registry so that the phone identifies itself as a normal phone rather than a smartphone and it seemed to work.

Is there a similar thing we can do in Android so that the device identifies itself as a normal phone?

Thanks
