For example for iPod nano 2g it is posted at 2010-03-08, for Cowon D2 at 2010-02-02. I think a lot of work done and the status does not correct.
For example:
"The current release of Rockbox's graphical installer, RockboxUtility, does not support the 2nd Generation Nano, but support has been added to SVN and you can use RockboxUtility if you compile it yourself from the latest source code."
But it is not true.
