It's official - Apple's iPhone can now boot Linux.

According to the Linux on iPhone blog and reports in popular media, the iPhone Dev Team responsible for the iPhone 2.2 firmware jailbreak has posted a port of linux for the iPhone.

At the moment it's more of a proof-of-concept than a functional linux installation, but it's a great start. Although support for the touchscreen, wireless, and sound have yet to be implemented (along with a slew of other features), we have faith that the iPhone Dev Team will continue to work hard to make the iPhone into one of the world's smallest and most powerful Linux machines.

Check out this Youtube video showing linux on the iPhone:

So, I guess the obvious question now is - what practical applications would an iPhone running Linux have? Anyone have any thoughts on that one?
