If your iPhone is not turning on, you may want to try "resetting" the phone. If the phone is turned off, you will need to hold the Power key (On the top of the phone) and the home key on the front of the phone. You will need to do this for about 10 seconds or until the apple logo appears on the screen.
You may have to try this a few times.
