The long awaited handset now launched. Apple chief Steve Jobs has announced the fourth generation iPhone at the WWDC 2010. When he launched this new iPhone within 2 hours every tech news site on the planet has a headline of this new iPhone on the site. It is complete overhaul of the iPhone 3GS.

Apple iPhone4 has many features different from iPhone 3Gs. Steve Jobs claimed that iPhone4 is the thinnest smartphone on the planet and at 9.3mm thick. It's 24 percent thinner than the iPhone 3GS. The most interesting features, differ form the 3GS are better camera, LED flash, faster processor (the Apple A4), a much improved screen (very high PPI), gyroscope for pitch, roll, and yaw, front-facing camera, and, of course, iOS 4.

iPhone4 has the same screen size 3.5-inches but it has higher resolution screen at 326 pixels per inch. So the resolution of the screen is 960x640 pixel which is so far the highest we've seen on a smartphone. Apple gave the name “Retina Display” to this display. Retina Display means the pixel density so high that it's beyond what your retina can see. In simple language it gives much higher quality text and pictures.

Now let’s talk about another important feature camera. iPhone 3GS has 3.2 MP camera while in iPhone4 has 5 Megapixel camera with a 5x digital zoom. Illuminated sensor and built-in LED flash also available which allow you to take amazing pictures even in low light and dark environments. HD video recording and front facing video conference camera is also available. FaceTime technology enables users to make video calls. Front facing camera is to make video calls. Apple also created iMovie for iPhone which allows you to edit your videos on the phone itself.

iPhone4 comes with iOS 4, the newest version of the world’s most advanced mobile operating system. It includes Multitasking, Folders, Enhanced Mail, Deeper Enterprise support and Apple’s new iAd mobile advertising platform. With Multitasking, users can now instantly switch between any of their apps; easily organize their apps into collections by simply dragging one app on top of another; Users can change the name of any folder at any time. The iPhone 4 runs on the A4 processor, the same one that’s found in the iPad. The new 3-axis gyroscope is “perfect for gaming” according to Mr. Steve. Because of the new hardware and battery combination it increases the battery life. 40% improvement in battery life.

Some other new features are also included like 802.11n Wi-Fi support, dual microphones for noise suppression, quad band HSDPA/HSUPA with speeds of 7.2Mbit down and 5.8Mbit up and of course a micro SIM, just like the iPad

From my point of view iPhone4 has many interesting and improved features. I like it and it is also worth to buy. It will come in the market between June to September all over the world. What say guys??? Are you willing to buy the iPhone4.
