iPod touch 8GB blackra1n help

i just got my ipod touch 8GB and i want to jailbreak it, i was told to use the blackra1n up but im having problems, first i had a missing dll "qtcf.dll" and then i put it in the system32 dir and it didnt work so then i was told to put it in the same dir as blackra1n.exe so i did that and now im getting a new error "The procedure entry point QTCF_CFUniCharGetUnicodePropertyDataForPlane could not be located in the dynamic link library QTCF.dll." and i cant get it to work.
