Steve Jobs officially announced the iPhone 4 at today’s WWDC 2010 keynote, and boy is it impressive. Sure, we already knew what it looked like already (thanks to some illegal manuevers by a certain other tech blog), but having Jobs introduce the phone and detail all of its internal specs is certainly nice. Available in either black or white, the biggest upgrade in the iPhone 4 is a new high-res IPS display, called the “Retina Display,” which has 960 x 640 pixels, four times the amount of the 3GS. With 325ppi pixel density and a 800:1 contrast ratio, Apple says that looking at the screen is as easy on the eyes as reading a book. Apps currently available in the App Store will automatically benefit from the resolution bump, but developers can fine tweak them so that they look even better.
Also new is a front facing camera whose main purpose is video chat via an app called “FaceTime” that works via WiFi only (though that WiFi is now 802.11n). The rear camera has been bumped to 5MP, with a new lens that has LED flash to improve low light photos and HD video recording at 720p/30fps.
The A4 processor that currently powers the iPad is the iPhone’s new CPU. In terms of new design, a stainless steel band goes around the phone, acting as an antennae. The battery is slightly larger, with an estimated battery time of 7 hours of 3G talk, 6 hours of 3G browsing, 10 hours of WiFi browsing, 10 hours of video, and 40 hours of music.
The iPhone 4 hits stores June 24th for $199 for the 16GB model, and $299 for the 32GB model.
