iPhone 4G Official Video HD



When creating iPhone 4, Apple designers and engineers didn't start with a clean sheet of paper. They started with three years of experience designing and building the phones that redefined what a phone can do. iPhone 4 is the result of everything they've learned so far. And it's all contained in a beautiful enclosure a mere 9.3 millimeters thin, making iPhone 4 the world's thinnest smartphone.

What's new

• Front-facing video chat camera

• Improved regular back-camera (the lens is quite noticeably larger than the iPhone 3GS)

• Camera flash

• Micro-SIM instead of standard SIM (like the iPad)

• Improved display. It's unclear if it's the 960x640 display thrown around before—it certainly looks like it, with the "Connect to iTunes" screen displaying much higher resolution than on a 3GS.

• What looks to be a secondary mic for noise cancellation, at the top, next to the headphone jack

• Split buttons for volume

• Power, mute, and volume buttons are all metallic


What's changed

• The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic in order for the cell signal to poke through. Tapping on the back makes a more hollow and higher pitched sound compared to tapping on the glass on the front/screen, but that could just be the orientation of components inside making for a different sound

• An aluminum border going completely around the outside

• Slightly smaller screen than the 3GS (but seemingly higher resolution)

• Everything is more squared off

• 3 grams heavier

• 16% Larger battery

• Internals components are shrunken, miniaturized and reduced to make room for the larger battery
