Skype 3.6
Skype is a little piece of software that lets you make free calls to anyone else on Skype, anywhere in the world. And even though the calls are free, they are really excellent quality. If you and your friends, family or business contacts are using webcams, you can also make free video calls. You can even call landlines and mobile phones at really cheap per minute rates (and there's no setup or subscription fee). 

With Skype’s free software – by the way, it works seamlessly with your internet connection – you can chat away with free Skype-to-Skype calls and never worry about cost, time or distance. Share the love and get your friends to download Skype so you can talk, chat or make video calls for nothing. You can also make local, long distance and international calls to phones and mobiles at great rates too.
