A new iPhone, a new record.
Apple said Monday that it sold more than 4 million new iPhones 6s in the first 24 hours they were on sale, breaking the previous record for pre-order sales.
The news is hardly surprising. Each time a new iPhone model has come out, it has broken sales records. Apple last week announced two new iPhones, both with bigger screens than their predecessors: a 4.7-inch model called the iPhone 6, and a bigger, 5.5-inch model dubbed the iPhone 6 Plus.
