As you can see at the next video (Spanish) the package manager fot the iPod Touch is very interesting is like synaptic or the apt repository. In the app's showed you can see a console with all the natives commands. It would be very powerfull and amazing. Also on February Apple will introduce the iPhone/iPod Touch SDK, if now there are amazing applications imagine on february.
You can download the iPhone/iPod Installer.app Installer.app
