With other Skype users you can:
- Make free Skype-to-Skype voice and video calls over 3G and WiFi.
- Share video calls on Skype with people on iPhone, PC or Mac.
- Talk face-to-face or show what you’re seeing with front- and rear-facing cameras.
This, of course, means that you can now use Skype to make video calls with the iPhone 4’s front-facing camera, previously the domain of Apple’s FaceTime application
