hi, i'm just wondering if i can replace the housing of may bb curve 9300 to bb 8520. i accidentally scratch the screen of my bb curve and i dont have a screen protector and the scratch was deep and im planning to change the housing but the problem is they dont have housing for bb curve 9300 here in Philippines because its still new and Ive searched that bb 9300 and 8520 have the same size. if they have the same size will it fit?
