How to Remove iPhone Apps From Phone Applications Library

1. Make sure the phone is on and navigate to the 'Home' screen where all icons of the iPhone applications show on the screen. If you've ever moved the icons or rearranged them on the screen, you already know the basics of how to delete apps from the library. If you've never done it before, don't worry - here's all you have to do in three simple steps.
2. With the application icons showing on the iPhone home screen, touch and hold one of them (it doesn't matter which one) until they all start to appear to wobble on the screen. You'll notice that you can touch and drag them to any spot on the screen now, even to the bottom 'favorites' area.
3. You'll also notice while the icons are wobbling that they now have a small X in the upper left corners. *(only on those apps you've added, not those that came with the phone.) Here's the secret step, touch the little black X and you'll get a pop-up dialogue box which warns 'Deleting [application name] will also delete all of it's data' and gives you two choices - 'Delete' or 'Cancel' - so click 'Delete' and you're done - the iPhone app is gone.
4. Press the 'Home' button (bottom center) and the icons stop wiggling on the screen and the 'X's' go away. Congratulations you've deleted an iPhone application!
