Please note that this "GSM" A1428 iPhone 5 model -- which is compatible with LTE bands 4 and 17 -- was intended for the North American market (AT&T in the US, Bell, Rogers, Telus, and affiliate brands in Canada, and Telcel in Mexico).

The iPhone 5 models, regardless of network compatibility, have a 4" (diagonal) widescreen multi-touch IPS LED-backlit 1136x640 native resolution (326 ppi) "retina display," dual cameras -- a rear 8 megapixel, 1080p "iSight" camera and a front 1.2 megapixel, 720p "FaceTime HD" camera, and 4G/LTE support, all packed in an aluminum "unibody" case with a glass front that is a mere 0.30 of an inch thick (color options include either a dark gray "slate" matte back and a glossy black front or a silver matte back and a glossy white front).

Each iPhone 5 device is powered by a 1.3 GHz dual core "Apple A6" processor, has 1 GB of RAM, and 16 GB, 32 GB, or 64 GB of flash storage. It also supports both 2.4 GHz and 5 GHz 802.11n Wi-Fi and Bluetooth 4.0 as well as packs three noise canceling microphones, a bottom-mounted headphone jack, and a new USB 2.0-based Lightning port for connectivity.

Apple estimates that the iPhone 5 models provide "up to" 40 hours of audio playback, 8 hours of talk time on 3G, 8 hours of Internet use on 3G, 8 hours of Internet use on 4G/LTE, 10 hours of Internet use on Wi-Fi, 10 hours of video playback and 225 hours of standby time.

In the US, this "GSM" A1428 iPhone 5 was available locked to and subsidized by AT&T with 16 GB, 32 GB or 64 GB of storage, for US$199, US$299, or US$399, respectively, with a two-year contract. It also was available unlocked and contract free at a premium.

As first reported by Engadget, this A1428 iPhone 5 model was phased out starting on March 26, 2013, and A1428 iPhone 5 models sold starting on April 12, 2013 were revised with AWS (1700/2100 MHz) support. EveryiPhone.com documents the later iPhone 5 device as its own model for clarity.
