Apple launchs of Iphone was really great, and more than 500000 units is sold in only 5 days!
You will need to activate the iphone in order to use it! The activation is done by AT&T and with Itunes! This activation of the iphone is not really great because you must subscribe to AT&T and to Itunes :(
I think that you can easily find some trick on internet to activate your cellular.
