While we're in the hacking mood, let's look at another hack that's surfaced ... the hacked 6th-gen iPod nano.
The hack is the brainchild of developer James Whelton who managed to bypass the device's cache comparison to install a Springboard hack.
The springboard hack is just the removal of a app and creation of a blank space. Not that amazing, but whats important is the bypass of Nano's cache comparison, which compares any modded SB file and reverts it if it doesn't like it, this opens up the possibility of hacking and modding, while not adding bootloaders or any of that fun stuff.
The hack has uncovered some hidden features of the iPod nano that Whelton hopes to be able to unlock shortly:
Next is the discovery in some of the device's plists of reference to support of Movies, TV Shows, Apps, Games, vCards, Calender events and so on, with a few other cool things like a passcode lock. With the bypass I figured out, I hope to enable these pretty soon. It seems like the OS is a rehashed version of the previous Nano's OS.
