Similar situation here, I got it to show in the taskbar, I can add my device but when I try to configure the bluetooth so I can wirelessly sinch, it doesnt work. For me this is the third time that I have upgraded to 4.1 OS and have never been able to synch wirelessly, I think in my case it is simply that my dongle is not supported, I will try with a nother type soon to see. And again I lost my modem tethering ability when it upgraded to 4.1 It sees the modem and tries to connect but then it simply says that it has a bad username or passsowrd. I have done this both manualy and with the verizon access manager.
