Last time we wrote about My3G , a jailbreak app that made face time calls over 3G possible. However you needed to jailbreak your Iphone first. Since jailbreak is not around and Green Pois0n is under development [ETA 10/10/10] , we have an Iphone 4 app named Tango that makes its possible do video calls over 3G & WiFi to iphone or any smart phone .
Tango is an entertaining video calling service that connects people around the world in an exhilarating new way. Tango features
- Free Video calling to your friends around the world
- Call between Iphone and other smart phones on 3G WiFi
- Invite Friends via email
- Switch and swap cameras like face time
