You can now do video calls using Skype Android app on these supported handsets.
Skype had introduced video calling feature on limited Android handsets till now. How limited? 4 to be exact: The Nexus S, Xperia neo, Xperia pro and Desire S were the only phones given the privilege to use video calling feature. But today Skype has increased their support for 17 more Android phones.
The list of newly supported handsets are:
Galaxy S II
Xperia mini pro
Do keep in mind though that if your phone has already received the Gingerbread update then you will be able to use switch between front and back cameras as video source on your device. But if you are using Android Froyo then it has limitation of using the back facing camera only.
