I managed to get Skype on the X51v working again. I hope that apple with its LCD pixel integrated camera is sucessfull and that in the not so far future I can talk with video and the screen is also the camera.

Now that would be something.

X51V has a built-in bluetooth device and I used it with sony ericsson's headset. That was not bad. But sometimes I believe that the bluetooth and wlan devices interfere and sound quality droped quite often.
