Chart: iPhone 5 first weekend sales compared to earlier iPhone models (chart)

Five million iPhone 5s sold its opening weekend, making it the fastest-selling iPhone of all time, likely because it was available in more countries this time. It took 74 days to sell 1 million of the original iPhones; the iPhone 5 doubled that  number just in pre-orders. We take a look back at first-weekend iPhone sales to see how the franchise has grown.
