[anotherphoneuser]

Okay so I bought a Blackberry Curve 8520 from a friend a week ago. He told me the previous user(which was his friend) dropped the phone and replaced the screen, then it had a blank white screen from then on. When I charge the phone, LED lights come on, so obviously, it still works, and when I connect it to the computer, it recognizes it. I need to know how many and what models of screens are there for the Curve 8520, because I'm planning on fixing this ASAP... But other than that, is it just the screen or is it something else?
