I don't care for video calling to be honest, I think it's a waste, I guess it could be potentially cool though, in naughty and nice ways lol.
Anyways
all I want from this 3G iPhone is video recording, GPS, a nice a battery and internet that's noticeably quicker than the current gen iPhone. Those features along with a decent price and the apps store/2.0 software/sdk and I will be set for a long time.
