I have an 8GB and it's an 4th gen touch. I dropped it on my hard wood floor with out meaning too. It slid out of my hand an hit the ground I think screen side down. Now on the right hand side of the top of the screen and is kinda rectangular yet oval with little dots in it with a line slowly growing across the top. Is it going to die on me? It was my birthday gift from my parents (18th) and we couldn't really afford it but they got it for me anyway. I can't afford to get a new screen at the moment and I need it to keep in touch with a couple friends who are having a hard time. Help? Any tips?
