Unfortunately, we never actually heard what the fraud was, but that's not too surprising -- if there was a way to defraud AT&T's ordering process, it's unlikely they'd shout it from the rooftops anyway. And it's also not likely that we'll never know how many customers were actually affected. NYC is a big city, but there's no way we'll see official numbers on how many people couldn't buy iPhones because of the steps taken the other night. Considering that iPhone sales are off the charts in most markets anyway, it's doubtful that online sales in NYC missing for a day or two would make a dent in the numbers.
In other words, nothing to see here. But just in case you were in NYC and trying desperately to buy an iPhone via the AT&T site last night, you can now go to it.
