Can someone explain what google voice actually does on the iPhone? I have had the app for a few days and whenever I try to call someone through the app (even on wifi, and even to another google voice number) it routes the call though my cell phone. I might as well just delete the app and make the call through the actual phone since that's all it seems to want to do. Anyone care to explain the point of the app and the service since?
(sorry if I am hijacking the thread, let me know if you want me to and I will make a new thread)
