Skype client seems to work well on the TC70 including video via the front and rear facing cameras. Audio can be switched between the top front speaker (handheld mode) and the bottom front speaker (handsfree mode) and quality of audio and video is good on a reasonable broadband connection. Tested also via a 3G WiFi hotspot and it still worked but was better with audio only since the video was choppy and caused the audio to break up periodically. Tested client APK is attached for anyone wanting to try the same.
