So what is new about the iPhone 4?
Design: This new iPhone is slimmer than the previous model, with glass on the front and back, and stainless steel around the edges, and the boxy design might make it easier to hold in your hand.
Camera: Actually there are two cameras — one in the front and one in the back. The back camera has 5 megapixels instead of 3 (like the old model), a 5x zoom, and an illumination sensor. It also includes an LED flash on the back and a tap-to-focus feature. But best of all, the iPhone can now record HD video, 720 pixels at 30 frames per second, to be precise. With the built-in video editor, you can edit and share your HD videos without ever transferring anything to your computer.
Display: To go along with the HD video capability, the new iPhone has an improved “retina display” of 326 pixels per square inch, which is 4 times as many pixels as the old iPhone. Jobs was sure to point out that the human eye can only distinguish around 300 pixels per square inch.
Faster: The iPhone 4 comes with the new Apple A4 Chip, the same one used in the iPad. The battery is also larger, which means more usage time: 4-7 hours of talk time, 6 hours of 3G browsing, 10 hours of wi-fi browsing, 10 hours of video, and 40 hours of music playback. Whoa!
iOS 4.0: What? The iPhone’s new operating system has been officially named iOS 4.0. With a faster chip, the new operating system includes some really great improvements, multitasking being one of the highlights. It also includes folders for your files, video chat (with the camera in the front of the phone), and iBooks.
iAds: Apple has integrated its new mobile advertising platform, iAds, into the new iPhone operating system. Apparently this is meant to support developers and keep the cost of apps down. I can imagine Apple will make a little money with this, too.
Prices and Ordering: The 16GB version will sell for $199 and the 32GB for $299. Both sizes are available in black and white, and pre-orders start on June 15th.
