Is there a free app that lets you make free phone calls in a wifi area for an unupdated iphone g3?

-And recieve phone calls. What would be the name of the app?Textfree with voice

TalkaTone



Both work with Wifi. The first one will give you a number, but may not be your area code, so people calling you without LD included in the voice plan, will be charged.



The second one used your Google Voice number and as long as you are on WiFi you can text and talk yourself stupid, for free.
