This status is based on the progress the freemyipod team has made so far. This is mostly a summary of reverse engineering and 'janitorial' work required to run end-user software like Rockbox or Linux.

Annotations

  1. 1.0 1.1 The "Nano" 6G and 7G are something entirely new, that doesn't seem to have much in common with the older generations of the Nano series. We don't yet know how these devices works and if we want to do something with them at all.
  2. 2.0 2.1 We need a new exploit to execute code on this device.
  3. 3.0 3.1 Nano 5G support is implemented in a tethered fashion via wInd3x, where we re-use parts of the original Apple boot chain which negates the need of some features.
  4. UART is not really needed here as we can already access the device via USB.
