Apple’s new iPhone 4: A4 CPU, HD video, high-res screen, video chat, 3-axis gyro for $199/299, June 24
Apple CEO Steve Jobs announced the iPhone 4 at the company’s Worldwide Developers Conference (WWDC) yesterday. The phone sports a high-resolution screen, thin new (though repeatedly leaked) design, front-facing camera for video chat, the iPad’s A4 processor, HD video capture and playback, a three-axis gyroscope, and the newly-renamed iOS 4.
The iPhone 4 will be available starting June 24 for $199 (16GB) / $299 (32GB) in either black or white, on a 2-year contract– and yes, it’s still tied to AT&T in the U.S.

As if one prototype of Apple’s upcoming fourth-generation iPhone being left in a bar and delivered to a tech blog weren’t enough, a second prototype iPhone has now found its way into some Vietnamese forum posters’ hands. Unlike the Gizmodo bloggers, however, these people had no worries about damaging the phone and took it apart to reveal whatever wasn’t already known. At this point we’re left wondering if Apple will have anything left to surprise us with when the new iPhone launches next month.

iFixit has followed up on its teardown of the new Apple iPad with an analysis of the chips inside. The Apple A4 CPU inside is a “package on package” design, with 256MB of Samsung SDRAM stacked right on top of the CPU, providing some benefits for both latency and power consumption. The CPU is most likely an ARM Cortex A8 design, paired with a PowerVR SGX 535 GPU– meaning that the iPad’s internals are identical to the iPhone 3GS’, except for a jump in CPU clock speed from 600 MHz to 1 GHz.
Anand compared the iPad to Google’s 1 GHz Snapdragon-powered Nexus One phone, finding the iPad was quicker in some tests. However, the two devices were running different operating systems and the iPad has a much larger battery (which may allow for Apple to more aggressively push performance over battery life), thus limiting the usefulness of the comparison.
