With a 2 year contract, the 16GB model will cost $199 and the 32GB model will cost $299. The models go on sale June 24th and the two options now are white and black.

Size: “Thinnest Smartphone on the Planet”

The iPhone 4 is 9.33 mm thick, which is 24% thinner than the iPhone 3G. There are external buttons for volume adjustment and mute.  The second mic on the top of the phone is, in fact, for noise cancellation. The back is made of stainless steel for strength and glass is used for scratch resistance and optical quality.

5 Megapixel Camera

They also packed in a micro sim tray and a camera with an LED flash (on the back). The camera is 5 megapixels and has 5x digital zoom in the camera. The camera also records HD video (720p at 30 fps). The LED flash can stay on while shooting the video. Not only that but you can edit the videos and pictures before you share them.

The iPhone 4 is powered by Apple A4 chip, which is larger and includes an A4 processor. Apple boasts that it allows 40% more talk time (around 7 hours), 6 hours of 3G browsing, 10 hours of WiFi browsing, 10 hours of video, 40 hours of music and 300 hours of standby.

Retina Display

No, it’s not a Mission: Impossible eye scanner. The new display technology increases pixel density by 4 times in the same amount of space. It has 326 ppi and an 800:1 contrast ratio which is 4 times better than 3GS. It utilizes IPS technology for better color and viewing.


A 3 axis gyroscope is built into the iPhone which allows for better pitch and yaw. With the inclusion of an accelerometer, the iPhone 4 will have 6 axis motion sensing.
