I listen to audiobooks on my Blackberry Curve and am looking for an MP3 player that has these features:

1. Keyboard control of fast forward and reverse. (With the trackball, you HAVE to look at the screen, which is dangerous while driving. With the keyboard, you could do it by feel.)
2. Keyboard control of pause and restart
3. Jumps to the next or previous file by keyboard control.
4. Remembers where it left off when it closes and restarts at the right place.(Does anyone know what this feature is called?)
5. Sequentially plays all the files in a folder or playlist
6. Pauses and restarts after a phone call

Nice but not absolutely necessary:
7. Allows me to set bookmarks
8. Responds to Bluetooth pause and restart

I'm trying out Podtrapper, and it's pretty good, but it doesn't do #3, 7 or 8.

Thanks for any suggestions.
