Nice with firmware 1.10, a bit higher than the 1.04 that's the latest available from the iRiver global site.
However, I can see that the korean iRiver site has published firmware 1.12 that is either available as a zip-file or distributed automagically with the new iRiver PLUS4 software. I assume that we can't get an english version of PLUS4 yet but the 1.12 firmware should be ok.
Does anyone know how to get it and maybe share a link? Tofuman perhaps?
