I just had a Fo who had the old iphone and he siad that he has used it overseas and that if you turn the data roaming off then you are fine. If you look that is the default setting. I am not going to use it to make calls but it is just one more way for my wife to get me without having to go thru schedule. I will use Truphone and skpye from my laptop to call her back. I will post with how it all works out from CDG.

To everyone who has posted here, thanks for all the great info, it has help tons!!
