iPhone 4S (16GB) Black AT&T
Specs / Features
Although the iPhone 4S looks like the iPhone 4 before it, it is considerably more powerful and most notably unveils a new voice-controlled "intelligent assistant" named Siri.
Like the iPhone 4, the iPhone 4S uses the same all stainless steel body design with an ultra high-density 3.5-inch, IPS, LED-backlit 960x640 326 ppi multi-touch "retina" display, dual noise-cancelling microphones, mobile and data antennas integrated in the "metal band" that wraps around the sides of the phone, and a chemically hardened "aluminosilcate" glass front over both the display and a black or white frame and the chemically hardened black glass back, too. Both the front and back have an "oleophobic" oil repellent coating as well.
However, the iPhone 4S is a "world phone," supporting both GSM and CDMA networks (UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz), and CDMA EV-DO Rev. A (800, 1900 MHz), and the "antenna automatically switches between send and receive." It supports 802.11b/g/n, Bluetooth 4.0, and HSDPA of up to 14.4 Mbps, too.
The iPhone 4S also has dual cameras -- an 8 megapixel HD video/still camera (1080p at 30 FPS) with a "backside illuminated sensor," and an LED flash on the rear and a VGA quality video/still camera on the front designed for video conferencing over a Wi-Fi network with Apple's included "FaceTime" application.
It is powered by a dual-core "Apple A5" processor, has 512 MB of RAM, and has 16 GB, 32 GB, or 64 GB of internal storage.
Apple reports that the iPhone 4S provides "up to" 40 hours of audio playback, 14 hours of talk time on 2G, 8 hours of talk time on 3G, 6 hours of Internet use on 3G, 9 hours of Internet use on Wi-Fi, 10 hours of video playback and 200 hours of standby time.
