Not sure why this comment was down voted, as this *is* a duplicate thread.
I've been trying to activate AT&T service using iTunes and the phone itself for the past hour. About 20 activation attempts at this point. No success just yet.
Just in the past minute I received the message "The activation server could not be reached". This is not the activation attempt timing out after 3 minutes. It just plain can't connect. So to say their activation infrastructure is overloaded right now is an understatement.
You figure to activate 200,000 phones an hour, they'd need to be able to handle around 110 activations *per second*. However the reality is they'll probably need to deal with something around 1 to 1.5 million phones this weekend, with far in excess of 110 attempting to activate at a given time. As with the 3GS and onward, they've failed to handle this load -- and I wonder if they care, since they only have to handle this activation crush on 1-2 days, and not have to care as much the rest of the year.
