iPod nano 3rd Generation Port

Summary

Rockbox currently doesn't run on the 3rd generation iPod nano. The freemyipod (formerly Linux4Nano?) project has cracked the firmware encryption and developed a simple tool for running code on the 3G Nano. See http://www.freemyipod.org/wiki/Status

Port Status

Currently no one has begun porting Rockbox to the device. A port can begin whenever someone takes interest.

Hardware

This device is similar (internally at least) to the Nano 2G. It also a shares a lot in common with Ipod Classic.

Entering DFU mode on the Nano 3G is acheived by doing a hard reset as with all other click wheel based ipods (i.e. hold Menu and Select), but instead of releasing this key combination, you hang on to it whilst the apple logo appears, and eventually the screen will go black.
