As anticipated, Apple has announced a new sleeker iPhone at the annual Apple's Worldwide Developers Conference (WWDC), powered by the A4 chip, introduced with the iPad.
Apple's CEO Steve Jobs has unveiled the new iPhone 4 during a keynote speech, The iPhone 4 is just 9.3mm thick, 24 per cent thinner than iPhone 3GS. That's the thinest smartphone on the planet according to Jobs. A new slightly bigger battery promises 40 per cent more talk time.
The combination of the new battery and chip should mean up to 40 per cent more talk time, 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 time. Jobs called the new iPhone: "Beyond a doubt, the most precise thing and one of the most beautiful things we’ve ever made."
New design and features
The iPhone 4 comes with a new design, front facing camera, micro-SIM tray, new volume buttons and a mute button. The Micro SIM tray is now on the side, while the camera plus LED flash is on the back of the phone. The bottom of the iPhone 4 has a mic, 30-pin connector, and speaker, and the top has headset, a second mic for noise cancellation, sleep-wake and gyroscope. The iPhone 4 add a three-axis gyroscope for measuring angular velocity. It can figure out pitch, roll, and yaw; and rotation about gravity. The gyroscope plus the accelerometer provide six-axis motion sensing. There are also new CoreMotion APIs that developers can call for extremely precise position information - ideal for games.
5 megapixel sensor
The iPhone 4 will come with an improved 5 megapixel sensor, 5x digital zoom and LED Flash, along with the ability to record HD video, 720p at 30 fps. The iPhone 4 will also come with built in video tools for editing and sharing footage. You can add titles, changes themes, and use music from your iTunes library, while Apple has created a version of its iMovie consumer video-editing application for the iPhone.
Retina display for better images
Using something called Retina display, the iPhone 4 will come with a much improved display, with shaper clearer text at text at 326 pixels per inch, double the 163 pixels per inch resolution of the iPhone 3GS. Both text and images will look better using the new technology Jobs told the room full of developers, although technical hitches are causing delays.
For Jobs’ patented (well, probably not, but it should be) 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— a feature called FaceTime - between iPhone 4 phones over Wi-Fi only - at least through 2010. Jobs said Apple needs to “work a little bit with the cellular providers in the future”. You can switch between cameras and chat in landscape or portait mode.
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.
Environmentally, the new iPhone is arsenic free, BFR-free mercury-free, PVC-free, and made from highly recyclable materials.
It comes in sizes up to 32GB of storage (the same as the iPhone 3GS) and includes quad-band HSPDPA/HSUPA networking with a maximum of 7.2Mbps down and 5.8 Mbps up.
“That’s theoretical because the carriers don’t support it yet,” said Jobs.
There’s also 802.11n Wi-Fi wireless networking, an improvement from 802.11g in the previous model.
Pricing and availability
The iPhone 4 will come in black and white, at $199 for 16GB and $299 for 32GB (with the same qualifications and two-year contract with AT&T as in the past) in the US. Apple will also add an 8GB iPhone 3GS for $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. UK pricing has yet to be annonced.
The iPhone 4 goes on sale in the U.S., France, Germany, the U.K., and Japan on 24 June, with pre-orders starting on 15 June. 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 $29 dock and a $29 case that comes in different colours.
