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.
Read on for our full coverage of Apple’s fourth-generation iPhone.
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.

As expected, Apple is currently working on its next-generation iPhone. Following the company’s yearly cadence, the fourth-gen iPhone is apparently due for release on June 22. According to the latest rumors, the phone may be called “iPhone HD,” packing a new processor from the same family as the 1 GHz Apple A4 found in the iPad (which is likely an ARM Cortex A8), along with a 960×640 display (4x higher resolution than the current iPhone’s 480×320) and possibly a front-facing camera for video chat. iPhone OS 4.0 may introduce multitasking for third-party apps, as we reported earlier.
As usual, there are also rumors of a CDMA-based variant for Verizon. The Wall Street Journal reports that the GSM iPhone would continue to be produced by Hon Hai (Foxconn), but the new CDMA version would be made by Pegatron, a subsidiary of the Taiwanese firm ASUSTeK Computer. No word on whether the iPhone 4G will include 4G wireless support (Sprint’s WiMAX or Verizon’s LTE), but given that America’s 4G networks are still in their infancy, we’re guessing Apple will stick with 3G.
There’s also a new video out of a screen, apparently from the 4G iPhone, that seems to match the photos we saw earlier. If accurate, we’re looking at a slightly larger screen (3.7″ vs. 3.5″) and slightly taller body than the current iPhone.
