iPhone 4: Everything you need to know about the iPhone 4

Read this article to learn everything you need to know about the iPhone 4.

On Monday, Apple has officially unveiled its new iPhone 4 after a couple wild, unprecedented months of leaks. Sure, it looks exactly like we expected it to (Steve compares it to an old Leica camera), with a glass front and back.

As expected, the iPhone 4 was announced today during Steve Jobs’ keynote at WWDC. Its flagship features are, of course, the extremely high resolution screen, video chat capability with FaceTime, and the sexy new form factor. But there’s more to the 4 than that, and even those seemingly self-explanatory new features deserve a closer look. Let’s see just what Apple’s done here with its biggest update to the iPhone since the original.

Apple iPhone 4 New Features

The Body of Apple iPhone 4

We’re all pretty familiar with the new body, since it was really the focus of Gizmodo’s exposé. In fact, that was pretty much the limit, since they couldn’t do much else with a dead, locked phone. The new design is more squared off, with a flatter back, creating a stronger shape in both your hand and eye. It’s not trying to hide the buttons, but rather showing off their careful placement and clean lines.

The Display of Apple iPhone 4

The new 3.5-inch “Retina” IPS LCD display sports 326 pixels per inch, and is 960 by 640 pixels. They’re calling it “resolutionary.” Hmm — Apple puns. 960×640 will be a meaningless number to most people, but the resolution nerds among us will recognize three things about it right off the bat. The contrast ratio is higher, too, at 800:1.

The Cameras of Apple iPhone 4

The new 5-megapixel rear camera is a decent improvement. I complained recently about cameras trying to resolve too much detail on a tiny sensor, and the iPhone camera will continue to to that, I’m sure, but the larger lens can only make things better. The backside illumination, too, should really improve low light performance, as well as the LED flash.

My previous post on iPhone OS 4 suggested that it contained top 9 new features to be expected about iPhone OS 4. Obviously, any new features will not be for iPhone OS 4, but for the freshly-dubbed iOS 4, clearly a different beast.

The Hardware of Apple iPhone 4

The iPhone 4 runs on the A4 processor, the same one that’s found in the iPad (or near enough). Jobs claims a 40% improvement in battery life due to the efficiency of the A4 (plus the 16% larger battery): 7h 3G talk, 6h 3G browsing, 10h Wi-Fi, 10h video, 300h standby.
