iPhone 4s

Background

iPhone 4s is the fifth generation of the iPhone, a device that combines a widescreen iPod with a touchscreen, mobile phone, and internet communicator. It retains the exterior design of its predecessor, iPhone 4, but is host to a range of improved hardware specifications and software updates compared to the previous model. Integrated software and hardware changes support the introduction of new user interface and functions by Apple. Highlights include a voice recognizing and talking assistant called Siri, personal computer independence, cloud-sourced data (iCloud) and an improved camera system. A selection of the device's functions can be controlled by voice. The iPhone 4s was unveiled at Apple's Let's Talk iPhone event on October 4, 2011 in Cupertino, California. Apple started taking pre-orders for the iPhone 4s on October 7, 2011 in seven initial countries (United States, Canada, Australia, United Kingdom, France, Germany, and Japan) with a first delivery date set for October 14, 2011, and available on that same day for direct store sales in those countries. It was released in 22 more European, American and Asian countries, including Ireland, Mexico and Singapore on October 28.
