A few days ago I dropped my Thunderbolt from no higher than a foot and a half off the floor, and it landed in the perfect position to crack the screen. There's 2 pretty big cracks that run from one side to the other (they meet in the center so its like a multiplication sign "X"). Anyways, the phones still works fine, touch screen is responsive, so it looks like the damage is just cosmetic. My question is, would buying a digitizer fix this? I saw some on amazon to $25 - $40. I heard it can be a bit of a pain to replace them yourself, but I don't mind giving it a shot if this is what they are for. Also, please don't move this to the thunderbolt forums. This relates to any phone that has a cracked screen. Thanks.
