Visa Blogging: Personal Interests: Technology: iPhone: Complete Comparison Between iPhone 4S and iPhone 4
The iPhone 4 is a touchscreen slate smartphone developed by Apple Inc. It is the fourth generation iPhone, and successor to the iPhone 3GS. It is particularly marketed for video calling (marketed by Apple as FaceTime), consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. It was announced on June 7, 2010, at the WWDC 2010 held at the Moscone Center, San Francisco, and was released on June 24, 2010, in the United States, the United Kingdom, France, Germany and Japan. The iPhone 4 runs Apple's iOS operating system, the same operating system as used on prior iPhones, the iPad, and the iPod Touch. It is primarily controlled by a user's fingertips on the multi-touch display, which is sensitive to fingertip contact. The most noticeable difference between the iPhone 4 and its predecessors is the new design, which incorporates an uninsulated stainless steel frame that acts as the device's antenna. The internal components of the device are situated between two panels of chemically strengthened aluminosilicate glass. It has an Apple A4 processor and 512 MB of eDRAM, twice that of its predecessor and four times that of the original iPhone. Its 3.5-inch (89 mm) LED backlit liquid crystal display with a 960×640 pixel resolution is marketed as the "Retina Display".
The latest operating system release is iOS 5.0.1. In October 2011, the iPhone 4S was announced, which retains the same form factor but includes many upgrades such as the A5 processor, iOS 5, and an improved camera.
The iPhone 4S is a touchscreen slate smartphone developed by Apple Inc. It is the fifth generation of the iPhone, a device that combines a 3.5 inch (89 mm) touchscreen iPod, mobile phone, and internet communicator. It retains the exterior design of its predecessor, the 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. It will be available on 100 carriers in 70 countries overall, including AT&T, Verizon, and for the first time, also for Sprint and C Spire[8] customers in the United States. In Japan it will be available for au (a KDDI brand) and Okinawa Cellular, for the first time.
