Seems like the iphone 4g has some antenna problems. They calling it Antenna gate. The calls were being dropped when you touched the two antennas. Steve Jobs promised to give free bumpers that will have solve the problem.
8 June 2010
Steve Jobs is launched the Iphone 4G today at WWDC on 7 June 2010. He was having some wifi problems during the iphone 4g release due to traffic congestion. Some one is going to loose their “Job” after the iphone 4g demo failed due to wifi problems.

Display
- higher optical quality and scratch resistant glass screen
- Sharper display with 326 pixels per inch quality. He said that 300 pixels per inch constituted the limit of the human retina and so things will start to look like continuous curves at that level. Total resolution is 960x 640pixels
Other features include:
- The 5 megapixel camera does HD video recording of 720p at 30 frames-per-second
- A4 chip

Engineered Glass
All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass — the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever. It’s also recyclable.
Retina Display
The 960-by-640 backlit LCD display boasts a pixel density of 326 pixels per inch, making it the highest-resolution phone screen ever. To achieve this, Apple engineers developed pixels so small — a mere 78 micrometers across — that the human eye can’t distinguish individual pixels. That makes text remarkably sharp and graphics incredibly vivid. IPS technology also provides excellent color and contrast from almost any viewing angle.
Stainless Steel Band
Created from our own alloy, then forged to be five times stronger than standard steel, the CNC-machined band is the mounting point for all the components of iPhone 4. The band provides impressive structural rigidity and allows for its incredibly thin, refined design. It also functions as both iPhone 4 antennas.
Apple A4 processor
Apple engineers designed the A4 chip to be a remarkably powerful yet remarkably power-efficient mobile processor. With it, iPhone 4 can easily perform complex jobs such as multitasking, editing video, and placing FaceTime calls. All while maximizing battery life.
Gyro Accelerometer
iPhone 4 is the first phone with a built-in three-axis gyroscope. When paired with the accelerometer, it makes iPhone 4 capable of advanced motion sensing such as user acceleration, angular velocity, and rotation rate. Translation: More motion gestures and greater precision for an even better gaming experience.
Camera LED
The iPhone 4 camera shoots gorgeous 5-megapixel photos and stunning HD video. And with its advanced backside illumination sensor, it captures beautiful images even in low-light settings. The built-in LED flash does double duty. When you’re taking pictures, it works as a flash. When you’re shooting video it can stay on to light up the scene. And on the front of iPhone 4, the built-in camera is perfect for making FaceTime calls and shooting self-portraits.
MIC Speaker
While most phones have only one microphone, iPhone 4 has two. The main mic, located on the bottom next to the speakers, is for phone and FaceTime calls, voice commands, and memos. The second mic, built into the top near the headphone jack, is for making your phone and video calls better. It works with the main mic to suppress unwanted and distracting background sounds, such as music and loud conversations. This dual-mic noise suppression helps make every conversation a quiet one
Multi Touch
With its large Multi-Touch display and innovative software, iPhone lets you control everything using just your fingers. How does it work? A panel laminated on the glass senses your touch using electrical fields. It can register multiple touches at once to support advanced gestures such as pinch to zoom, two-finger tap, and more. The panel then transmits the information to the Retina display below it.
