iPhone 4S +
The iPhone 4S is a touchscreen slate smartphone developed by Apple. It is the fifth generation of the iPhone, a device that combines a widescreen iPod with 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. Much of the device's functions can be controlled by voice, and this frees people from looking at and touching the device for many tasks.
