I must share the same problem here with perhaps further information. I tested the phone Sony Ericsson Xperia X10 (Android version 2.1 und 2.2.1) with the latest Android Skype Version with the following countries (my location is Austria):
- - Austria
- France
- Hungary
- Romania
- USA
In each case the user was logged to a computer and (in the same network) to the Sony Ericsson Xperia X10 as well.

From Smartphone (me) to Computer (other end of the line) works OK. You can understand the other person perfectly talking and the person understand you (quality 80% - 90%).

When you have a conversation from smartphone to smartphone then you get to hear background noises. Just like a bad movie sound recorded by a cheep camera
(quality 20%-30% or less)
I also tested Android Skype throw WiFi (WLAN) and 3G -> both cases the same quality as above.
