iPhone 4 Features: This Changes Everything. Again.

Steve Jobs unveiled the much awaited next generation iPhone at today’s WWDC 2010 Keynote address and it looks exactly like the lost next generation iPhone prototype.

Apple is calling their fourth generation iPhone - iPhone 4, after various rumors and speculations that it might be called iPhone HD.

Apple believes its “the biggest thing to happen to iPhone since iPhone”. Find out all you wanted to know about Apple’s new iPhone 4 after the break.

Here are some of the major features of Apple’s new iPhone:

FaceTime:

iPhone 4 comes with two cameras, a front facing camera in addition to a camera at the back.

The front facing camera will allow iPhone 4 users to make and receive video calls. You can switch between the two cameras during a video call with a tap of a button. You’ll also be able to make calls in both portrait and landscape mode.

But you can make and receive video calls only between two iPhone 4s. It will be interesting to see if iPhone apps like Skype will allow users to make video calls to other Skype users on computers or other mobile devices. Video calling works only over Wi-Fi.

Steve Jobs has mentioned that the feature is Wi-Fi only in 2010 but they’re working with cellular providers to allow video calls over 3G.

However, if iPhone 4 is jailbroken then you should be able to use jaillbreak apps such as VoIPOver3G, 3GUnrestrictor to make video calls over 3G. So if you’re an existing AT&T customer then it might be a good reason to stick to the unlimited data plans.

Retina Display:

iPhone 4 will be running at a resolution of 960x640. Apple is calling the iPhone 4 display, the Retina Display.

Apple has managed to pack four times more pixels in the display as compared to previous iPhone models. The pixel density of iPhone 4’s display is 336 pixels as compared to 163 pixels in iPhone 3GS thus making it the smartphone with the highest-resolution screen currently.

iPhone OS 4.0 which has be renames as iOS 4 will automatically make iPhone apps work on the higher resolution Retina display.

HD Video Recording:

iPhone 4 users will be able to shoot movies in high definition HD (720p) up to 30 frames per second with audio. Apple has also announced a new iPhone app called iMovies for iPhone to enable iPhone 4 users to shoot, edit and share videos.

Better Camera:

iPhone 4 comes with a 5-megapixel camera as compared to iPhone 3GS 3.2 megapixel camera.

But more importantly iPhone 4’s camera comes with built-in LED flash. So you’ll be able to finally take low light photos with iPhone 4.

A4 Chip:

iPhone 4 will be powered Apple’s A4 chip. The same chip that powers Apple’s iPad.

A4 is very good with very power management as we have seen with the long battery life of iPad.

Improved Battery Life:

The battery of iPhone 4 is bigger. So with the bigger battery and A4 chip, Apple has managed to improve battery life as compared to iPhone 3GS.

• Talk time:

  
  

  • Up to 7 hours on 3G (iPhone 3GS: Up to 5 hours on 3G)

  
  

  • Up to 14 hours on 2G (iPhone 3GS: Up to 12 hours on 2G)

In my opinion, the 40% improvement in battery life is one of the most significant improvements in iPhone 4 as poor battery life was one of my biggest gripes about iPhone 3GS.
