what is the price of iPhone 4?
what are the main features of  iPhone 4 ?
when will iPhone4 launch in India ?
Now it comes to an end for these questions.
Well, the iPhone 4 is finally here! The fact is, those who really wanted to buy the iPhone 4 bought one from online stores abroad or cajoled the relatives into getting one for this on the way back from abroad. Why it has arrived in India now is a bit perplexing, considering we are hearing rumors of the inevitable iPhone 5 launch. However, there are still lots of people who will want to buy the iPhone 4, simply because they may not have been able to order it from abroad or just wanted the extra assurance that the warranty will work in case of any issues. The good thing is, the new iPhone isn't locked on any networks, which means anyone on any network can enjoy the phone. However, Airtel and Aircel will be offering some special tariff packages if you buy the phone from them. While this doesn't have the dual core processor goodness, it isn't a slouch in any way whatsoever- has been gobbling up HD games all along, without any complaints. The Retina Display is one of the best we have seen across all smartphones, and the extremely high resolution really helps with the multimedia performance as well. If you are upgrading from a previous generation iPhone, want to shift to the iOS ecosystem or just interested in seeing what the hype is about, we would strongly urge you to check it out. And don't let the dual core argument sway your decision, since this phone isn't lagging in terms of performance in any way, whatsoever.

Retina display with 960-by-640 resolution
The Retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp.

Video calling with Face-time
People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With just a tap, 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 or to the new iPod touch over Wi-Fi. And it works right out of the box. No other phone makes staying in touch this much fun.

HD video recording and Editing
Shoot your own movies in high definition. Capture impressive video even in low-light settings, thanks to the advanced backside illumination sensor and built-in LED light. Then edit and create your own mini-masterpiece right on iPhone 4 using the iMovie app — with Apple-designed themes, titles, and transitions. It’s available on the App Store for $4.99.

Apple A4 chip with Multitasking 
iPhone 4 introduces a whole new way of 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.1 This smarter approach to multitasking is available only in iOS 4.

5-megapixel camera with LED flash
Take beautiful, detailed photos using the 5-megapixel camera with built-in LED flash. The advanced backside illumination sensor captures great pictures even in low light. And the front-facing camera makes it easy to take self-portraits.
