This is the green version of skype. You can intall it on your X10.
1. Copy the zipped file to your SD card and then insert the SD card into X10 (or copy the zipped file to X10 directly)
2. unzip the file
3. click the icon of Skype 1.2 and the system will intall it for you automatically.
Sorry, members, one of my colleague installed it on one X10 before i post and it worked. But today, i tried again on another device, it fails. i have deleted the software and also will look for another availble one for you.
