have been using frin and am pretty amazed by the quality for being on a mobile. I have also experienced alot of backround noise but plugging in a wired headset took all this away. I am only 3g here it is good but with wifi on no problems at all. I tried qik for the first time yesterday and loved the video but it is a one way system the person that doesn't initiate the connection has to push a button to talk dealbreaker for me.
I haven't tried it w/ BT yet but I wonder if BT earpiece has to be A2DP capable?So using wired headset took care the background problem? Cool, I got to try it.
I tried to use Bluetooth, it didn't work, just FYI.
