My screen went blank tonight. The light flashes at the top and the home button and others light up, but nothing on the screen to see. It still reacts, though - i ran my finger across like I was unlocking it and it vibrated. I have had it less than a month. I have pulled the battery multiple times to no avail. Anything else I should try before I take it into Verizon tomorrow? Will they give me a hard time when swapping it out? Thanks.
