The fifth model of Apple's smartphone, introduced in October 2011. Housed in an almost-identical case as the iPhone 4, the 4s sports numerous internal changes, including a fast dual-core A5 CPU, dual antennas and an eight-megapixel camera with improved optics. The iPhone 4s debuted with the iOS 5 operating system, which provides cloud storage for a user's content (see iOS versions and iCloud). See iPhone, iPhone 5 and iPhone 5s.

The Siri Intelligent Assistant
A highly touted feature of the 4s was Siri, a voice-based command system that answers questions and takes dictation. For more details, see Siri.
