The display of the phone has great pixel density, leading to higher-quality images from Apple’s Retina display technology. The model is available in 16Gb and 32 GB capacity, and comes in either black or white. The 5MP camera has 2592 x 1936 pixels, autofocus, LED flash, and check quality. It also features a front facing camera, touch focus, geo-tagging, and an HDR option. There is a non-removable lithium ion 1420 mAh battery, allowing for up to 300 hours of standby and up to 40 hours of music time.
