I just signed up for Skype $2.95 Unlimited US and Canada Land Line and Moblie calling and it works great! I use my phone a lot while at home so the majority of all my calling is going to be from my room. I'm going to be changing my iPhone plan this week to the 450 mins, since I won't nearly be using my ATT mins that much since I will make most of my calls via skype when I'm in Wifi. I was wondering if anyone else is going to be doing the same. The only thing I need to do is setup Skype Caller ID which is free with my subscription although I have to buy a credit to confirm I own my mobile phone which will allow me friends to see my iPhone number when I call them from skype.
