i just had to "activate" my iphone to make an international call... to call from the US to another country. out of the box, it just won't let you. to get this set up, i had to answer a series of vaguely strange questions... i guess to verify it's me, but still they are weird: 1) what is my home mortgage company 2) what city i used to live in a loooong time ago 3) name a place where i used to work 4) what state was my SSN set up in and a few others. strange. not sure why it's such a problem to call internationally on ATT. on my Tmobile phone, i just picked it up and dialed. there was absolutely NO verification of any kind. so... just throwing this out there. why the hell is ATT so anal about calling outside the country? they even asked where i was going to call. the answer, of course, was "does it matter?"
