Thank you, but I'm afraid to try jalibreaking it.
The last time I tried editing firmware, I bricked a media player. I don't think I could do something so complex (at least, unless I had no other alternative...)
I was hoping for some sort of premade software?
I might try it if there's no other choice, though... Since you use it,I have a question: does the collection manager permit mass-editing of some sort, such as selecting a lot of books and adding them to / removing them from collections? What is the interface like?
