I have a Curve 8330 and have had little trouble with bluetooth connectivity using a usb bluetooth adapter with my Dell pc running Windows 7.

I upgraded to Blackberry Desktop Manager 6.0 and all the connectivity ended. I installed it (several times) and it works fine via a usb connection.

But it will not work other than the first time after going through the usb connection again.

I reinstalled Desktop Manager 5.01 and it works via bluetooth, but I have to log out and in every time to get it to connect.

It is dropping the bluetooth connection all the time.

Why did RIM release such a piece of junk (6.0 Desktop), with absolutely no support to get it to work via bluetooth synce.
