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.
