iPod Classic & 3G Nano Firmware Download
Alrighty, i've been poking around at the Classic's firmware image. It appears to be much larger than previous firmwares, and seemingly has no references to PortalPlayer - is this finally a build of OS X for iPod?
Only problem is it looks to be in the same 'format' as older iPod firmwares - i.e. it's not a DMG so don't expect 3rd party software to appear as easily as for iPhone.
