The Linux 2.6 kernel has been ported to Apple's iPhone platform, with support for the first and second generation iPhones as well as the first generation iPod touch. This is a rough first draft of the port, and many drivers are still missing, but it's enough that a real alternative operating system is running on the iPhone.
From the iPhone DevTeam:
What we have:
â€¢ Framebuffer driver
â€¢ Serial driver
â€¢ Serial over USB driver
â€¢ Interrupts, MMU, clock, etc.
What we have in openiboot (but hasn't been ported yet):
â€¢ Read-only support for the NAND
What we don't have (yet!):
â€¢ Write support for the NAND
â€¢ Wireless networking
â€¢ Baseband support
The current userland we're using, in the interest of expedience, is a Busybox installation created with buildroot, but glibc works fine as well, and we're going to build a more permanent userland solution.

EDIT: The instructions are missing the step that you have to select openiboot console from the menu before performing the "sudo ./oibc" step. Just be aware you have to do that if it seems like you're not getting a response from the oibc client.

If you're experienced with hacking/porting Linux and especially if you're experienced with porting Android, I'd definitely like to hear from you. Come chill in the #iphonelinux channel on irc.osx86.hu. Thanks. :)
