Apple's 4th-generation iPhone revealed ahead of launch

The fourth-generation iPhone prototype has found its way to Gizmodo, and after digging around have concluded that it’s the real thing. Not only does it show up in iTunes, Xcode, and System Profiler, but it has different product identifiers than the 3G or 3GS, and it’s packed with Apple-labeled components inside. But a number of new features and changes are evident just by holding it. It’s thinner than the current phone, with smaller internal components and a larger battery.

There’s also a front-facing camera, a larger and better camera with a flash on the back, a higher-res 960x460 display that’s slightly smaller than the current models, a second mic for noise cancellation.  It’s also three grams heavier than a 3GS, with a 16 percent larger battery.
