Hello, yesterday I was stepping into my car and of all days it was raining. My phone fell out of my pocket and the screen is cracked badly but still works. However, the bar with the back button, home, and the search lights up but does not work when tried to use, every time I want to switch apps I have to reboot my phone. Does anyone have a ballpark estimate for the replacement cost of the screen, and by the way AT&T dropped all of the warrantys on our phones without telling us.
