Two questions about iAudio 10

[sovietonion]

Hello! I'm considering buying the iAudio 10, and I'd like to ask two important questions before I make my final choice.

1. Can it sync properly with MediaMonkey? This includes not just the songs themselves but also playlists containing Unicode entries. (On my old C2, I ended up having to manually romanise the file names and recreate existing playlists with Playlist Creator. I'm hoping to avoid this hassle.)
2. Can it play m4a files?

Thanks in advance for helping me out!
