A few days ago I started to notice that my curve wasn't saving pictures. I read online to try a battery pull, I did and it worked, I could see all the pictures I thought were not saved (not sure where they were being stored or hidden). However then the problem appeared again today and it's not only the pictures but I can't delete anything, I hit delete and nothing happens, I can't rename videos or ringtones or pictures.

It seems that something is stopping it from updating the files, I mean they seemed to be saving but not showing it to me. What could be the problem? How can I fix it for good?
