June 07, 2010, 4:40 PM — The Apple iPhone 4, announced today by Steve Jobs at Apple's Worldwide Developers Conference, will be 24% thinner than its predecessor at 9.3mm thick, contain a front-facing camera, and offer greatly improved battery performance (up to 40% more talk time, according to Jobs).
Jobs described the phone as, "beyond a doubt, the most precise thing and one of the most beautiful things we've ever made" before highlighting a number of its new features.
The iPhone 4 will be priced at $199 for a 16GB model and $299 for a 32GB model, and it will go on sale June 24.
Other iPhone 4 Features
The new phone will have 32 gigabytes of storage, a gyroscope (which will allow for more precise motion detection), and HD video recording capability.
The phone also will have a improved screen resolution: 326 pixels per inch with heightened contrast. Jobs told the crowd that 300 pixels per inch is the limit of the ability of the human retina to view images.
It also will have three antennae built into the structure of the phone's body that will provide the iPhone 4 with the ability to work with Bluetooth; WI-Fi and GPS; and UMTS and GSM.
In my opinion, the display difference in the example Jobs shows is striking. While I've been dissatisfied by the fuzziness on the iPhone 3GS's text--something I liken to the difference between standard definition TV vs. HDTV--the text on the iPhone 4G looks sharp and crisp, with no pixelation. Additionally, the colors are more vibrant, and edges are smoother and sharper.
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.
Camera and Screen Details
The IPhone 4 comes with two cameras: One on the front for video conferencing, and one on the rear for photos and video. The rear-facing camera has been upgraded to 5 megapixels--up from 3 megapixels on the iPhone 3GS--and it can record 720p high-definition video.
Also included is an iPhone version of iMovie, which will let you edit video clips on the phone, splice them together, add titles to your videos, and so forth. (The app will set you back $4.99 from the App Store, Jobs told the packed audience at San Francisco's Moscone Center).
