How do you do video chat on the SGII though? I'm guessing you need some software like Skype, etc., which means your friend also has to have installed, you need to be friends with them, and so on. On the iPhone, FaceTime is built right into the phone app—just call your friend and press "Video Chat". No need to worry about setting up an account or downloading anything else. The only thing you need to coordinate with your friend is to make sure they have an iPhone.
Skype would probably be the choice plus you can have group video chat.
It is odd that there isn't any ready-to-go Samsung app for it (I have an SGII) or at least I didn't see one yet.
It's not a big surprise though since not all phones which use the Android OS have a front facing camera so it would be up to the individual phone manufacturers to add an app if their phone has a front camera.
