iPodLinux is an open source venture into porting Linux onto the iPod. So far, we have successfully ported a customized uClinux kernel to the iPod, and written a simple user interface for it dubbed podzilla. Additional applications and modules have been written, adding many capabilities not found in Apple's firmware.

iPodLinux is currently safe to install on 1st, 2nd, and 3rd generation iPods. Development is currently on-going on later generations of iPod, including the fourth generation click wheel, mini, U2, Photo/Color, Nano, and Video.
