Hello I have a Flying Touch III 10.1 inch Google Android 2.2 Tablet PC I purchased a usb keyboard for it, which works fine. I just converted my tablet to a VOIP phone. My Tablet comes with a built in mic and headset jack. I was wondering is it possible to add an external bluetooth headset(with mic for making calls.) Or simply an external mic wired or not. (The USB keyboard works.) Note tablet does not support bluetooth.
