okay so i have a blackberry bold 9700 and i was listening to music in the car and i wanted to listen to a different song so i pressed next and all of a sudden it froze so i left it till it didnt freez anymore but i didnt know my battery was dead, so i charged it and now all my pics, songs voice notes ect are gone but they're still in the memory card. i took it out and put it back in it didn't work. but when i put my memory card in a different blackberry it worked. any ideas?
