So here is my story. I dropped my iphone 4 while i was at the gas station then a pick up truck decide to run it over. So the front glass shattered and so forth. I picked up some replacement parts and decide to fix it. Everything seems fine except it wont power on unless i plug into a power outlet. It would shut off when i unplug it?? and the screen for emergency calls would pop up. The strange thing is when I plug it into my computer itunes doesn't read it and my phone is stuck on the apple logo restarting?? weird..can anyone help me??!! =(
