The eagerly awaited Apple iPhone 4 has lots of great new features like FaceTime video calling, as well as many updates and improvements on iPhone 3 features and apps.

FaceTime is the video calling we’ve all been waiting for. iPhone4 to iPhone4, it only takes one tap of a button, even in the middle of a call, and you’re face to face with your lover, partner, or best friend. Or watching your granddaughter across the country playing dress-up. With two built-in cameras made for video calling, you can switch back and forth. One camera on the front is calibrated with the right focal length and depth of field for capturing your image while holding the phone in your hand, while the camera on the back can capture whatever it is you’re watching live and stream it to your caller. No screen name or special account needed; it’s all included.

Speaking of the cameras, the resolution of the graphics on iPhone 4-everything you see from pictures to e-mail to web pages-is crisp and incredibly detailed. Apple engineers have developed a smaller pixel, enabling them to cram 400% more pixels into the 3.5 inch screen, resulting in striking images, even at an angle. The advanced engineering produces a wider range of viewing angles than other LCDs, whether playing games or sharing video clips with a friend. This Retina display also has better contrast, giving the user whiter whites and blacker blacks for enhanced readability of text, including iBooks, as well as more striking pictures.

The touch-screen itself is harder and more durable than previous models, as well as more scratch resistant, due to a chemical strengthening process. A coating on the screen repels oils and keeps the screen cleaner.

Another great new feature of the iPhone4 is folders for your apps. Just like the folders on a computer, each folder holds several apps within it, meaning you can fit a whole lot more apps on your home screen. Simply touch and hold an app until it jiggles, the drag it into an app of the same category. For example, all your games can go in one folder while travel apps nestle in another. iPhone4 will give each folder a name based on its contents, although of course you can rename it anything you want. Using iTunes on your home computer, you can create folders and sync it to your iPhone4. Pretty cool.

The multitasker interface makes life easier by letting you switch quickly and conveniently between apps you’ve used recently, then jump right back to where you were. Listen to music or a ball game while surfing the web or checking e-mail. Receive a Skype call while other apps are running. GPS can continue to run, update your position, and give voice directions, turn by turn. The music automatically lowers while the GPS directions are given.

Uploading photos to a service taking too long? No need to wait. It can continue in the background while you go on to a new task.

There’s so much more you can do with the iPhone4. Take videos in high definition; even in low light situations. Edit video into a movie on the fly. Read e-books. Hear in noisy places. Use Visual Voicemail. Read e-mail. Surf the web. Oh, yes. It also make phone calls.
