sure no problem, all you got to do is put un install itunes and re-install the newest version ofitunes, then take your ipodtouch and iphone, put them both in dfu mode, and hook them up, and itunes should requnize both of them as in recovery mode, and then you can restore them. (do it for both, so it will requnize both devices as new., and not get confused between the two, ok i hope i helped you) dont jailbreak and you will never get any issues like this !
