Apple today announced that it had sold two million iPhone 5 smartphones in the first 24 hours of pre-orders last week, more than double the previous record set in 2011. U.S. mobile carrier AT&T also said its sales broke earlier records. “iPhone 5 pre-orders have shattered the previous record held by iPhone 4S and the customer response to iPhone 5 has been phenomenal,” said Philip Schiller, the head of Apple’s marketing, in a statement issued Monday. Schiller said iPhone 5 sales had “topped two million in just 24 hours,” over twice as much as last year’s iPhone 4S first-day sales.
