update you phone;s software using the ovi suite. before doing that, move all your pictures, videos, music etc to memory card and see if this does not help
get another nokia and put the data on that phone, then transfer to your blackberry. pc suite wont sync with bb no matter what. or else open the file where the data is located and drag to your bb.
oh no, that happened to my friend's 9700 as well. we fixed his phone by moving all his music, pictures and videos to his memory card. try not to save anything on your phone's internal memory.
