Apple has released their latest mobile device after months of rumors and speculation. iPhone 4 debuted on Monday, and Apple CEO Steve Jobs said that this is the “biggest leap forward” the iPhone has made since it was introduced in 2007.

iPhone 4 is the fourth-generation of iPhone and Jobs said at a tech conference in San Francisco that it has “one of the most beautiful designs you’ve ever seen. This is without a doubt the most precise thing and one of the most beautiful things we’ve ever made.”

iPhone goes on sale on June 24, and below are ten reasons why you should buy this “beautiful” phone.

Sharper screen

With 326 pixels per inch, Jobs said the iPhone 4’s “retina display” screen is years ahead of anything else on the market. It makes text remarkably sharp and graphics incredibly vivid with excellent color and contrast from almost any viewing angle.

Gyroscope

iPhone 4 has a built-in three-axis gyroscope. It makes iPhone 4 capable of advanced motion sensing when paired with the accelerometer. It means more motion gestures and greater precision for an even better gaming experience.

Thickness

At 9.3 millimeters (0.37 inches) thick, iPhone 4 will be the thinnest smartphone on the market.

Camera flash

Apple added a built-in LED flash in iPhone 4’s camera that does double duty. It works as a flash when you’re taking pictures, and it can stay on to light up the scene when you’re shooting video it can stay on to light up the scene.

Better camera

The camera  iPhone 4 shoots 5-megapixel photos and HD video. It also has a video-editing app called iMovie.

Video conferencing

Aside form the back-of-the-phone camera improvements, the built-in camera on the front of iPhone 4 is perfect for making FaceTime calls and shooting self-portraits.

Multitasking

iOS4, or iPhone’s operating system, makes iPhone capable of running multiple applications at once like listening to internet radio while checking your e-mail.

Stainless steel antennae

The band of stainless steel that goes around the edge of the phone as a trim isn’t just a design feature, it is actually the phone’s antennae.

Guts

Apple engineers designed the A4 chip that makes the phone faster than competitors and faster than the processor in the iPhone 3GS. It is a remarkably powerful yet remarkably power-efficient mobile processor which makes the phone capable of performing complex jobs such as multitasking, editing video, and placing FaceTime calls.

Multi-Touch

iPhone 4 lets you control everything using just your fingers with its large Multi-Touch display and innovative software.
