Is it legal, in terms of anti-trust law, for Apple to use only one carrier (ATT) in the US to distribute iPhone? I would like to ask someone who is familiar with the anti-trust law to look into this issues and see if there is a case to file an anti-truse case to Apple and make Apple to use more than one carriers in the US to carry iPhone.

Guess your complaining since some other countries have a law against it.
I'm guessing it's no problem in the states and that you'll have to live with it.

I wish it weren't so, since the dollar is so weak right now it's cheap as hell for me, a Swede, to buy stuff. Muwahaha!
