I've been using MilliTalk and it's a great phone app. It makes calling anyone anywhere fast and easy. And all MilliTalk to MilliTalk calls and texts are completely free.
You can get it too in the App Store, at http://alau.me/0h7v9a.
A few more things I love about MilliTalk: it adds another line to your iPhone, iPad, iPod touch and now even the iPad mini. It works over the data network so it won't use up your cell minutes. International rates are the lowest anywhere.
