iPhone 4:For which you can wait for Long

iPhone 4 introducer claims offers over 100 new features, though he would focus on only a handful for the keynote. The iPhone 4 looks like the iPhone prototype obtained under questionable circumstances by Gizmodo: stainless steel casing, all-glass front, and a design Jobs describes as the thinnest smartphone on the planet: almost 25 percent thinner than the iPhone 3GS.iPhone 4 will have volume controls on the side of the phone along with an accessible microSIM tray.This phone features a front-facing camera, and the back sports a microphone, 30pin connector for docking, and a speaker, while the top sports a second microphone for noise cancellation, sleep/wake button, and a headset input.

There are hundreds of applications which will fulfill your day to day needs.

Multitasking: Now you can run your favorite third-party apps — and switch between them instantly — without slowing down the performance of the foreground app or draining the battery unnecessarily.

Folder: Organize apps into folders with drag-and-drop simplicity. Get faster access to your favorites and browse and manage up to 2160 apps.

Check your Mail/Message: See mail from all your accounts in a unified inbox, organize mail by threads, open attachments in third-party apps, and more.

FaceTime Phone Calls: People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 over Wi-Fi. No other phone makes staying in touch this much fun.

Camera & iMovie: iPhone 4 will feature a 5 megapixel camera with a backside-illuminated sensor, which Jobs says increases the amount of light captured by the sensor, resulting in better photographs, particularly in low-light situations. The camera will also record HD video at 720p resolution and 30 frames per second, and the LED flash can be used to light video

No Longer iPhone OS 4: iOS 4: iOS 4 will have the features Apple outlined back in April, including a form of multitasking support (so applications like Pandora can stream music in the background while an iPhone user, say, surfs the Web in Safari), a unified Mail inbox that supports multiple services, home screen folders, a Game Center, and improved support for Microsoft Exchange and enterprise users.

Retina Display: ''Retina display'' with four times the pixel density of a typical LCD display at a whopping 326 pixels per inch—by far denser than anything else in the consumer electronics market. The result is a 3.5-inch display with a native resolution of 960 by 640 pixels that is actually a higher resolution than the typical human eye is capable of perceiving, when held at a distance of just 10 to 12 inches.

Video Calling: Front-facing camera in the iPhone 4 exists for one and only one purpose: video calls.The feature will initially be Wi-Fi only and operate iPhone 4 devices—no word in whether FaceTime will support, say, desktops or notebooks equipped with cameras. Users will be able to switch to the rear-mounted 5 megapixel camera on the iPhone 4 to let callers see what they’re seeing, or stick with the front-facing camera for face-to-face chat.

Spell checking: A built-in dictionary automatically suggests words and corrects spelling. It works in Mail, Notes, and other apps.

Wireless keyboard support: Pair a keyboard based on Bluetooth wireless technology with your iPhone.

HD Video Recording: iPhones 4 gives you ample opportunity to record and edit stunning HD video which gives you cristal clear HD video or else you can enjoy full length movie in it with very high resolution.
