Apple confirmed that the iPhone 5 topped 2 million sales in one day. This number is more that double what the iPhone 4S managed.

Demand for the device is so high, some pre-orders will be delivered to customers in October, rather than September as previously planned. Apple says most pre-orders will be delivered on September 21.

“Clearly it’s a blowout,” said Brian White, an analyst at Topeka Capital Markets who had anticipated sales of 1.3 million to 1.5 million units.

“iPhone 5 pre-orders have shattered the previous record held by the iPhone 4S and the customer response to the iPhone 5 has been phenomenal,” said Philip Schiller, Apple’s senior vice president of global marketing.

AT&T said its customers ordered a record number of the iPhone 5. The company’s subscribers ordered more of the new smartphone model than any previous iPhone both on its first day of pre-orders, said the carrier.

All of this pushed Apple’s stock to over $700 is after hours trading, a new record in valuation.
