Apple’s iPhone 4S has broken the previous single day pre-order record of 600,000 set by the iPhone 4. According to Apple, the iPhone 4S has been pre-ordered over one million times in just 24 hours.

“We are blown away with the incredible customer response to iPhone 4S,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “The first day pre-orders for iPhone 4S have been the most for any new product that Apple has ever launched and we are thrilled that customers love iPhone 4S as much as we do.”

Apple said that iPhone 4S will be available at all 245 Apple retail stores in the US beginning at 8 a.m. local time on Friday, October 14. Every customer who buys an iPhone 4S at an Apple retail store will be offered free Personal Setup service, helping them customize their iPhone 4S by setting up email, showing them new apps from the App Store, and basically helping them get everything running.
