Wow, after all the chatter I thought I'd be the only one ordering a 64gb; judging by the comments there are a bunch of us. I, too, got 64gb space gray, ordered in about a minute via the iPhone app. 1-3 days to ship.
Only problem is the shipping address must default to the one on file with your carrier, rather than the one you have set up in the app (I made sure ahead of time that my shipping address was to my work, but now it's shipping to my home, so I'll have to stay home from work to sign for it). Hopefully I can change it before it ships, but as of right now the only option is to cancel the order, and I'm not about to do that! Hmm.. I wonder if their call center will be slammed tomorrow.
Lesson learned - if you're using the app, double-check your shipping address!
Yea its easy to change, just go to bed, and change it on the account page after breakfast!
