The latest iPhone 5 is set for pre-orders tonight at midnight and will most likely sell out rather quickly. The main improvements include new earbuds (called earpods), a 4-inch widescreen Retina display, a beefier A6 processor, a slightly sexier aluminum enclosure, a new back, a thinner design, 4G LTE, dual-channel 802.11n 5GHz networking, a centered HD FaceTime camera, iSight camera with panorama mode, and a new charging/data port. Cool stuff.
