The latest iPhone has been unveiled by software giant Apple.
Phil Schiller, senior vice president of Apple, said the iPhone 4s looks similar to the previous iPhone4 model and shares its glass front and back.
He added: "But don't be deceived. Inside it's all new."
He said the new A5 chip in the device would allow it to use much faster graphics for gameplay, and would allow users to download data twice as fast as the previous model.
Mr Schiller added that its camera has five lenses, one more than the iPhone4, which will result in sharper pictures.
Speaking from a videolink to a press conference at Apple's California base, he also showed off a series of photographs he described as "stunning" which were taken with the new phone. The phone also allows users to take HD video.
Senior vice president of iPhone Software Scott Forstall then showed off the phone's voice recognition software, called Siri, which allows users to ask the phone questions and get answers.
He said it works as "your humble, intelligent personal assistant that goes everywhere with you and can do anything for you just by asking".
Mr Forstall said Siri understood the language and context of users' questions and then gave a series of examples by asking the phone about the weather, his diary and the stockmarkets. "I've been in the AI (artificial intelligence) field for a long time and this still blows me away," he said.
The phone will be available in the UK on October 14 - the same day as the United States. The 64gb version will cost £260, the 32gb £195 and the 16gb £130.
