I've never used Skype before so I'm not familiar with how it works other than it's supposed to be easy to use with an iPad. I went ahead and download the app based on the raves people give it here. From what I read in the description it's free if the person you call also has Skype right?. It also says you can call or text other contacts at low rates with Skype credit. I didn't give a credit card # when I signed up but was able to make a call to my wife's cell that wasn't using Skype. So my question is how does it charge you if you make a call to a phone that's not using Skype?
