Thomas Jarosch has been quite busy and worked a lot on the Rockbox port for Maemo, it is the direct result of the previous work on making it possible to run Rockbox as an app on top of operating systems. It is still early and there are things missing, but it is approaching usable really fast it seems

The work on the app for Android has also been progressing over time and even though it is still not available to download from the Android Market, the apk is updated regularly and pretty functional.
