What is new in the iPhone 4S?

Apple launched the latest version of its popular mobile phone, iPhone, in stores around the world this week. The launch of the iPhone 4S was watched closely by media and techno-enthusiasts as it was the first launch after the death of Apple’s revolutionary leader, Steve Jobs. The iPhone 4S is not different from its predecessor iPhone 4 in physical appearance, but is noted for the introduction of a voice assistant, Siri. The voice assistant is capable of voice recognition and talking back. Siri is expected to revolutionize the way mobile phones are used, with more accessibility given to people who are driving (or otherwise occupying their hands) and to those with visual difficulties. The drawback is that it needs an internet connection to function. The iPhone 4S also has an improved camera system (8MP) and uses iCloud, a cloud-sourced data platform.
