万众期待的 Apple iPhone 5 终于在 2012 年的今天来到了！设计上，它跟传闻的一样，有着 4 吋的屏幕（1,136 x 640，326ppi）、一体式铝制机身、背盖上下的天线开口。它的机身厚度为 7.6mm，比 iPhone 4S 薄了 18%；重量有 112g，轻了 20%。说了外面当然要说一下里面吧，它的核心用上了 A6 芯片，Apple 指它的速度比 4S 的快两倍。
网络方面，支持 LTE、HSPA+、EV-DO 和 EDGE 等。

Apple may be notoriously secretive and tight lipped, but the company appears to be getting worse and worse at actually keeping things under wraps. The iPhone 5 appears to be the most leaked handset in existence. Thankfully, the suspense is over, the next-gen iPhone is finally here and it does, in fact, go by the numerical title of 5. Just like the parts that have been circulating this is a glass and aluminum affair and, at 7.6mm it's a full 18 percent thinner than the 4S. It's even a full 20 percent lighter at 112 grams. It's all those amazing things and it packs a larger 4-inch display. The new version of Apple's Retina panel is 1136 x 640, which clocks in at a more than respectable 326ppi. It also sports better color saturation with full sRGB rendering

That new longer screen allows for an extra set of icons to be displayed on the home screen, and first party apps have already been tweaked to take advantage of the additional real estate. The iWork suite, Garage Band and iMovie have all been updated. Older apps will still work too, though they'll be displayed in a letterbox format until an update is issued. The tweaked ratio puts the iPhone 5 display closer to 16:9, but it's not quite there.

The most exciting news is likely the addition of LTE. There's still HSPA+, EV-DO, EDGE and all that jazz on board, but it's the true 4G that is really generating excitement.
