iphone 4

If you haven't watched the video yet, you probably should. It'll get you even more excited.
The hardware
The iPhone 4 will have its very own A4 chip, made by Apple. Very similar to the one in the iPad. If you own an iPhone you know how horrible the battery can be. Well, it has ben fixed; up to 7 hours of straight talk time and 6 hours of straight 3G internet usage. The camera has received some much-needed attention as well, it's now 5 megapixel, with LED flash. It can also shoot full HD 780p video. If you haven't already heard from the leak, there is also a front-facing camera for video chat, but there isn't any specs available yet for it. The body is now encased with optically laminated aluminosilicate glass with an oleophobic coating. In English, that means it uses super hard glass (30x stronger than plastic) with a built-in screen protector and a no-smudge coating. There is a steel band that goes around the device, with no new buttons. The new Retina display has the highest resolution display ever on a mobile device; 326 pixels per inch! There are two new microphones to help with noise cancelation–the one you put to your ear, and another on the bottom by the speakers. The new memory sizes are 16GB and 32GB, so more room and more speed.
Everything else
The feature that everyone is talking about is of course, the multitasking. Double tap the home button, and the screen slides up to reveal running apps; it's that simple. A new app being released by Apple is iMovie for $5.99. From what I can see from the website, it looks quite intuitive, and there most likely won't be too many features, as it should be. The iBooks app is no surprise, but it will also be available for download, probably for free. The front facing camera can be used in the Camera app, so it's much easier to take a picture with yourself and a friend now; before it was practically impossible, searching for the tiny shutter button. FaceTime works as an addition to the Phone app, and video calls can only be made with other iPhone owners. Hopefully third-party apps (like Skype) will have access to video-chatting, but it would be just like Apple to hold off on that and release it later as a "new feature". The folders feature works by simply holding an app until it jiggles, and then dropping it onto another app. The folder is automatically named with what category they were in in the App Store. There is also a orientation lock that can be enabled, but there isn't a physical switch like on the iPad. Mail now has a (much anticipated) unified inbox, and conversations can be ordered by thread. Unfortunately there were no updates to the iPod, Safari, or Maps applications. I was looking forward to the Turn-by-Turn directions, or a more feature-rich Safari. It will be available for pre-order on the 15th, and to buy on the 24th for the same old $199 price.
