Honestly can you wait until say Monday? What is it you need so bad that it cant wait? Was your current iPhone (if you had one) broken in some way? If you got a new iPhone, did you have to have it today?
Like anything else new and popular, in this world the "got to have it now" are going to whine every time with out fail. I dont care if its a new movie and people are lining up for it on day one, they will complain.
Honestly did you think it was going to be anything but a madhouse at the stores, on the phones, or on their web sites today? If not you have to be completely clueless.
I have an iPhone/.Mac account and I want the updates, but you know for my sanity, and the continuity of my current service, I will just sit here, drink a beer and watch you people go mad.
I bet when I do try Sunday/Monday I will have much fewer problems. Best of luck, I hope you have fun waiting on the phone.
