Just as expected, Steve Jobs unveiled the iPhone 4 at WWDC. Not surprisingly, the phone looks much like the prototype that Gizmodo acquired, with a steel frame, glass accents, front facing camera, and a camera with included flash on the back. The device comes in at 9.3mm, about 24% thinner than the iPhone 3GS, and what Jobs called “the thinnest smartphone on the planet.”
Another major feature is the “Retina display,” Apple’s upgraded screen for the iPhone 4. The resolution comes in at 326dpi, which along with some software magic makes for clear, smooth fonts and more vivid images. Jobs said the resolution is actually higher than the human eye can see (exaggeration, perhaps?). Either way, Apple expects it to be “years” before anybody matches this display.
The Apple A4 chip will power the device and is much smaller than the chips that have powered previous devices. But that’s because the device needs a bigger battery for all these new features: 40% more talk time, 6 hours of 3G browsing, 10 hours of Wi-Fi browsing ,10 hours of video, 40 hours of music, 300 hours of standby.
A new gyroscope feature along with new core motion APIs will enable all different types of motion in games. The upgraded camera now takes 5 megapixel pictures, and will take HD video at 720p at 30 frames per second. With this new camera, it’s time for a new standard app, and that’s iMovie for iPhone.
It essentially works like iMovie for the Mac OS Desktop, allowing the user to add transitions, titles and effects to videos captured on the device. Geolocation functionality would also allow the video to be geotagged. Apple will make iMovie available on the App Store for $4.99, jokingly adding “if we approve it.”
