Let’s first dig into the physical details of the new smartphone. The iPhone 4 measures 4.5 x 2.31 x 0.37 inches and weighs a mere 4.8oz – making it the thinnest smartphone yet.
The front and back are made of aluminosilcate glass, chemically strengthened to be 30 times harder than plastic, more scratch-resistant and more durable than ever before. In addition, the front and back glass feature an oil-resistant, fingerprint-resistant oleophobic coating.
Encircling the iPhone 4 along the sides is a highly-finished stainless steel band made of a custom allow five times stronger than standard steel.
You’ll find a 3.5 mm stereo headphone minijack on top and a microphone/built-in speaker on the bottom, along with the familiar dock connector interface.
The new Retina display measures 3.5 inches diagonally and features an awesome resolution of 960 x 640, a contrast ratio of 800:1 and a crazy pixel density of 326 pixels per inch (ppi). At this ppi, it’s more than the human eye can discern when the phone is held at a normal distance.
You’ll find two cameras on the iPhone 4 – a front-facing VGA camera and a 5 megapixel autofocus camera with 5x digital zoom, backside illuminated sensor, and built-in LED flash. You’ll also be able to record video at 720p resolutions at 30 frames per second and yes you’ll be able to use the built-in LED light with video recording. Apple is also introducing the iMovie app for the iPhone allowing you to perform video editing right on the iPhone itself for a mere $4.99.
On the connectivity front, iPhone 4 supports the following: * UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz)

* Bluetooth 2.1 + EDR wireless technology
On the sensor front, iPhone 4 features a built-in accelerometer, proximity sensor, ambient light sensor, and a new three-axis gyro. The three axis gyro when combined with the accelerometer provides 6 axis motion sensing such as up/down, side to side, forward and back, and pitch/roll. Expect some awesome gaming apps to utilize this new sensor.
Power-wise, iPhone 4 still has a built-in rechargeable lithium-ion battery but battery life has been improved to: * 7 hours of talk time on 3G
