...i can still recevie calls/txt? Okay so i had a blackberry pearl. I dropped it really hard on the floor and the screen got completley messed up. I couldnt call or text anymore or nothing. i figured it was messed up and left in it my drawer for like 8 months. Tonight i took it out cause i found it and put it in the charger, it turned on but the screen was just half black half white and i press buttons for like 10 hours and suddenly i started receving calls and texts!!! SOO crazy i knowww!!! i asked my mom to call me and text me and i could hear her and she could hear me and everything. it was awesome. So now it DOES work. but the screen is still messed up I cant see anything. But heres what im wondering can someone fix this for me? or is the phone completley done? like it still works soo good, its just the fact that I cant see anything, there able to replace that right? someone who has had theirs repaired pleeease reply to this!! I dont want to get it replaced cause i have soo many important messages saved on it. Please reply to this for me please itd be so appreciated! thanks you guys
