That doesn't mean it's good.
(My rage isn't over the fact that they're making fun of Apple; it's that the US versions are designed HORRIBLY. Other than that, pretty good devices.)
And the difference is? It's only integrated into the OS being that instead of tapping an app icon, then going to contacts, and then calling, you tap an app icon...go to your contacts....oh wait.
FaceTime Over 3G? Nope! Even the phones that could do video calling before the iPhone could do it over the cell networks. In my opinion, FaceTime is some of what a flawed system is. If they really want to kick FaceTime off, they need to open it to other devices that aren't just Apple products, and for god sakes, let it over the network!
