iPhone 4S pre-orders top 1 million in 24 hours

Apple says first-day pre-orders of the iPhone 4S topped 1 million, breaking the record set by last year's model.

Apple Inc. and various phone companies started taking orders for the phone last Friday. It hits stores this Friday.

First-day orders for the iPhone 4 were 600,000 when it launched last year. It was then sold in the U.S. only by AT&T Inc. The iPhone 4S is also sold by Verizon Wireless and Sprint Nextel Corporation.

The base model of the iPhone 4S costs $200 with a two-year contract. It has a faster processor and an improved camera compared to last year's model.

Apple shares rose $9, or 2.4 percent, to $378.80 in premarket trading Monday.
