I've just got a new Witstech A81-E and in the process of trying to get Skype to work over my WiFi connection I managed to un-install it, Skype that is. How do I re-install Skype and where do I get it from? It doesn't appear in any Market and the A81E is not mentioned on the Skype download site. Will Skype work over WiFi on this device? It works on my Nokia E72 mobile phone with WiFi.
