It's a great number but I want to see the global breakdown before we all join together in a great sigh of relief.
For the first time (correct me if I'm wrong) an iPhone was available for preorder in China. They have more mobile users than the rest of the pre-order countries combined (pretty close to 3x over in fact).
I want to understand if the numbers are inflated because the preorder was available to so many people or because the demand is so high.
