I woke up this morning to find out my blackberry would not turn on. I had it on and charging. No buttons work, pulled battery and put back in. Nothing. No water or any damage. Now when i pull the battery and back in, it turns on but you can barley see the screen and no buttons work. I have another phone coming in on monday. But what caused this to happen? Is there anything i can do so i can at least be able to use it this weekend? Phone is a at&t 8320
