Apple Inc received orders for more than one million iPhone 4S phones in the first 24 hours, topping the previous record of 600,000, the company said on Monday.

In the United States the iPhone 4S is being carried by three U.S. operators for the first time with Sprint Nextel joining AT&T Inc and Verizon Wireless as an iPhone seller.

Orders started just over a day after the company announced the death of its co-founder Steve Jobs.
