Apple iPhone 4S (GSM China)Released only for the mainland China market, and initially launched with China Unicom, the iPhone 4S (GSM China), model number A1431, is believed to be identical to the global iPhone 4S, except that the Wi-Fi capabilities have been modified to support the "WAPI" Wi-Fi standard as required by the Chinese government.

Like the global iPhone 4S, the China only variant 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.

The China-only iPhone 4S still is believed to be 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 China-only 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 8 GB, 16 GB, 32 GB, or 64 GB of internal storage (32 GB and 64 GB options discontinued September 12, 2012, 8 GB option introduced September 10, 2013 and discontinued altogether September 9, 2014).

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.
