I am curious what is the best way to make and receive calls on iPhone via Google voice over data/wifi and not over voice going against our att minutes now that they made calling free on Gmail?
Since that feature just came live yesterday, you need to give Google and developers some time to came out with a client, I am sure Google will added to the google search application and someone will come out with a client shortly
chill... it takes time!!! Remember that also they are probably finishing other apps to submit them once again to the App Store to see if they approve of them this time around..
