I have an Iphone 4, and I was just checking my email last night, suddenly the screen went crazy and pink vertical lines started appearing. Now my screen is just black with purple vertical lines on the left side of the screen. Its really faint, not bright at all. I'm able to reset my phone fine, I can even turn it off and slide the phone to turn off at the spot where the off slide thing is suppose to be if my screen was fine. I tried resetting it and restoring it, nothing helped. HELPP?
