10 reasons iPhone 4 is so cool

APPLE CEO Steve Jobs said the iPhone 4 is the “biggest leap forward” the iPhone has made since it was introduced in 2007, CNN reported.

At Apple’s Worldwide Developers Conference in San Francisco on Monday, he said: “This is without a doubt the most precise thing and one of the most beautiful things we’ve ever made.”

But besides being “beautiful”, what makes this iPhone different? Here are 10 reasons:

1 SHARPER SCREEN
With 326 pixels per inch –four times that of previous Apple phones – Mr Jobs says the iPhone 4’s “retina display” screen is years ahead of anything else on the market.

“Text looks like you’ve seen it in a fine printed book – unlike you’ve ever seen on an electronic display before,” he said.

2 GYROSCOPE
The iPhone 4 has five sensors, including a gyroscope. What does that mean for users? Probably cooler games
and apps. The iPhone 4’s internal gyroscope can sense motion on six axes. On Monday, Mr Jobs showed a demo where he pivoted in a circle, and the stack of blocks in an app spun with him.

3 THICKNESS
It will be the thinnest smartphone on the market, Mr Jobs said. At 9.3mm thick, it is 24 per cent thinner than the previous iPhone model, the 3GS, he said. The iPhone 4’s screen remains the same size as before, 3.5 inches when measured diagonally.

4 CAMERA FLASH
Apple added an LED flash to the iPhone 4’s camera, which lets mobile photographers shoot photos and video more easily at night.

5 BETTER CAMERA
The quality of the iPhone 4’s camera has improved over previous models’. The iPhone 4 shoots photos with 5 megapixels of resolution, comparedto 3 megapixels before.

The iPhone 4 also shoots HD video, and a video-editing app –called iMovie – which Apple will sell allows people to shoot, edit and share videos with the phone.

6 VIDEO CONFERENCING
In addition to the back-ofthe-phone camera improvements, Apple also added a second camera, which faces its user. This can be used for video conferencing, which Apple and Mr Jobs expect to be an emerging trend in the use of mobile phones.

7 MULTI-TASKING
The iPhone’s operating system, which Apple calls iOS 4, got an upgrade along with the iPhone 4’s hardware. Among the most-awaited changes is multitasking, which means that the phone can run multiple applications
at one time.

8 STAINLESS-STEEL ANTENNAE
The iPhone 4 is flat on the front and back, and a band of stainless steel goes around the edge as a trim. This isn’t just a design feature, Mr Jobs said. It’s actually the antennae. “It’s never been done before and it’s
really cool engineering,” he said.

9 GUTS
The iPhone 4 has a new processor – the A4 – which Apple says makes the phone faster than competitors’ and faster than the iPhone 3GS processor. 10 IMPROVED BATTERY LIFE The improved battery
life allows for 40 per cent more talk time, Mr Jobs said.
