I have a JB'd 3GS 32GB (via Blackra1n) and it's been perfect for a while now. All of a sudden yesterday I added a few tracks and this morning I get a message that there is no space available. There was 9GB of free space available the day before today. I went into the "about" area and it says 0 bytes available? Any way to restore back my space? I don't really want to re-jail break it, it's too customized.
