Apple's 4th Generation iPhone, the iPhone 4, was made official on June 7th at the 2010 WWDC and began shipping shortly thereafter.
iPhone 4 represents the third redesign of Apple's smartphone, with a boxier, thinner look than previous models. The front and back of iPhone 4 are glass, while the straight sides are stainless steel bands which double as antennas. iPhone 4 is .36 inches thick.
Apple has made some significant upgrades to iPhone 4 hardware over last year's 3GS. First, a faster A4 processor, similar to the one that's in the Apple iPad. Second, a new IPS display with 960x640 resolution and 326 pixels per inch. Third, a new front-facing camera. Fourth, a new battery for up to 7 hours of 3G talk time and 10 hours of Wi-Fi web browsing or video playback.
Camera details: there's an updated rear autofocus camera with 5MP and an LED flash. It's also been updated for better photo quality with a backside illuminated CCD. The rear camera can shoot HD video at 720p at 30 frames per second (FPS) and an iPhone version of iMovie for video editing will be available for $4.99 in the App Store. A new front-facing camera has also been added, which makes it possible to have FaceTime video chats on the go; at launch, video calls will only be available over Wi-Fi. |
