Skype on iPhone - free video calls!!

I gave Skype a try on my iPhone for the first time yesterday. I contacted my sister in Quebec to see how it would work and I was impressed. I was on a wi-fi network, which I am told is the best way to make a Skype video call and it worked very well. The sound was clear, the video acceptable. I was finally able to introduce my grand-daughter to my family. That was pretty cool.
