When I use FaceTime on my iphone - is it free?
Yes, it is. You just need to be connected to a wi-fi network.
See this thread concerning costs when enabling facetime from a phone call: http://www.mactalk.com.au/31/90652-facetime-free.html
It Is Free But IN iOS 5 You Must Be in Internet IN iOS 6 It Works Over 3g Edge wifi
