I installed CM7 and it works great. The BT works and I can pair BT headsets but have not tried out the audio connection successfully yet. Since my goal is to use it for Skype and SIP phone calls, a working headset or microphone is absolutely necessary. My questions are: 1. Has any body successfully make voip calls on NC yet? 2. If yes, what headset/microphone was used? 3. By Googling, I found this store (Barnes & Noble Nook Color 3.5mm C.SHINE Dynamic Driver Handsfree Stereo Headset | OrionGadgets.com) is selling headsets for NC. Does anybody know if the headsets works on NC?
