Ok so my cuzzin has a broken iphone 3gs and he went out and bought i brandnew one and kept the old one, he told me that the old phone the screen is in a million peices because of his girlfriend running it over. I asked if he was able to use it like tocuh it and it would work he said no. So what im askign is what could be wrong with it is the screen not working because of the screen being in a million peices or what should i buy the phone of him for 25 bucks i can replace the screen by myself but what else could be wrong
