I have a FAN account and after the AT&T nightmare last year this time I ordered directly through Apple. Got straight through on a White 64gb 4S, kept my unlimited data for $30, only thing is I was forced to upgrade to unlimited texting for $20 (which I expected). Was super smooth.
My wife was trying to order on her own plan, a White 16gb, and it crashed during AT&T verify. But the weird thing is Apple asked her to sign in, and then sent her an email guaranteeing her a phone on launch day when the AT&T servers are back up.
She has a link from Apple to sign up and order by Saturday the 8th to confirm, but I'm still unable to get through the AT&T crap servers.
Oh well.
