What types of USB devices will the iPod touch recognize? I was thinking you could use a USB type A/female to 30-pin/male connector, but I am not sure what would work without jailbreaking and further hacking. Do you think it would require a hack to get the said combination to work with an input device like an Apple keyboard? I know there is a keyboard dock for iPad, but not for iPod touch. Anyway, that's just one of many possibilities.
