In his long-awaited Worldwide Developers Conference keynote speech, Apple CEO Steve Jobs introduced the fourth-generation iPhone, termed the “iPhone 4″. Per Macworld, the iPhone 4 is 9.3mm thick, or 24$ thinner than the iPhone 3GS and includes new camera with an LED flash on the black, but a second, front-facing camera as well. There are new volume buttons, a mute button, plus a second microphone on the top for noise cancellation. Just like the iPad, it now incorporates a micro-SIM tray.

Apple has also engineered three integrated antennas into the design: one for Bluetooth, one for WI-Fi and GPS, and one for UMTS and GSM.

The iPhone 4 features a new screen technology called a “retina display” which operates at 326 pixels per inch, double the 163 pixels per inch resolution of the iPhone 3GS.

The new display measures the same 3.5″ inches diagonally, but at 960 x 640 it has four times as many pixels as the previous model with an 800:1 contrast ratio that’s also four times that of the iPhone 3GS. It uses the same IPS display technology as the iPad and the iMac for good color fidelity, brightness, and viewing angle.

The new handset also sports the A4 chip, which boasts both a small footprint and good power management. Apple went with the micro-SIM design to save space, mostly for a new battery that, coupled with the new chip, Apple says provides 40$ more talk time. The company says talk time is up from 5 hours to 7 hours; 6 hours of 3G browsing; 10 hours of Wi-Fi browsing; 10 hours of video; 40 hours of music; and 300 hours of standby.

Environmentally, the new iPhone is arsenic free, BFR-free mercury-free, PVC-free, and made from highly recyclable materials.

The handset includes quad-band HSPDPA/HSUPA networking with a maximum of 7.2Mbps down and 5.8 Mbps up.

There’s also 802.11n Wi-Fi wireless networking, an improvement from 802.11g in the previous model.

The iPhone 4 also add a three-axis gyroscope for measuring angular velocity and can figure out pitch, roll, and yaw; and rotation about gravity. The gyroscope plus the accelerometer provide six-axis motion sensing which can be combined with new CoreMotion APIs that developers can call for extremely precise position information.

The iPhone 4 has a new, 5-megapixel camera with 5x digital zoom and an LED flash. It also adds 720p HD video capture at 30 frames per second. The company has also created a version of its iMovie consumer video-editing application for the iPhone. With it, you can record or edit you videos (and add photos as well). Once the video has been recorded, users can add titles, changes themes, and use music from your iTunes library.

iMovie for iPhone will be available for US$5.

For Jobs’ “One More Thing” moment, he sat down on a chair to show off the iPhone 4’s video chatting capabilities. Using either of the two cameras, you can make video calls via a feature called FaceTime between iPhone 4 phones over Wi-Fi only (at least through 2010). Users can also switch between cameras and chat in landscape or portait mode.

The iPhone 4 will be available in both black and white, at US$199 for 16GB and US$299 for 32GB (with the same qualifications and two-year contract with AT&T as in the past). Apple will also add an 8GB iPhone 3GS for US$99.

Jobs said that AT&T is going to make “an incredibly generous upgrade offer.” If your contract expires any time in 2010, you’re immediately eligible for that pricing, for up to six months early eligibility. The iPhone 4 will be available from Apple and AT&T’s retail and online stores, as well as at Best Buy and Wal-Mart stores.

The iPhone 4 goes on sale in the U.S., France, Germany, the U.K., and Japan on June 24th, with pre-orders starting on June 15th. It will ship in 18 more countries in July, in 24 more in August, and in 40 more by the end of September.

Apple also showed off some accessories: a US$29 dock and a US$29 case called a Bumper that comes in white, black, blue, green, orange, or pink.
