oooo i do know a bit about ipods lol, this might interest u i dont know but ipods can record directly through the head phones socket at upto 98khz
to do it you will need to install something called podzilla onto it (it does not need the expensive apple or belkin recording attatchment which only records at 8khz), i think it records stereo, i know it works because i use it ocasionally with my ipod
podzilla is free and all the downloads and instuctions can be found by searching on google
