More than 3 million people have pre-ordered Apple's iPhone 4S, as the company gets ready to release their latest smartphone.
Bloomberg Businessweek reports that up to 3 million units may be sold in its first weekend on sale, which would double the number of iPhone 4's sold during its opening weekend in 2010.
JPMorgan & Chase Co analyst Mark Moskowitz said: "The early momentum of the iPhone 4S reaffirms Apple’s leadership in smartphones."
He also suggested that the high number of pre-orders suggests that early-adopters aren't overly concerned with the fact that there is very little new design with the product.
Most of the iPhone 4S's improvements come "under the hood", with a new dual-core A5 chip, an eight-megapixel camera capable of recording movies in full 1080p HD, iCloud and voice command system Siri.
Piper Jaffray Cos analyst Gene Munster has predicted that Apple could sell up to 25 million iPhone 4S's by the end of 2011.
The iPhone 4S goes on sale on October 14.
