VOIP on iPhone

I've often boasted to my friends that my iPhone is the coolest gadget I've ever owned. It's even cooler now with my new fav. app called Fring. Now I can use SKYPE on my iPhone and call anyone in the world, from any WiFi connect for nuthin'. Yes, SKYPE finally made it's way to a shoe phone! I should be using it pretty steadily next year while I'm on the road.
