Is it? My wife wants to talk to her mom back in Japan over skype video. Her mom has a PC with skype. If I understand correctly, my wife can: --Call her mom's computer on skype for a free video call --Call her mom's Japanese cell phone (non iPhone) for a free audio call Also if she does these with her iPhone's wifi on, no data will be used, but if she does it with 3G, then a lot of data will be used? ?? What can and can't be done is kind of confusing, and what uses data and what doesn't.
