well, let me tell you that i got something.
i created another account and i was able to save my shsh files.
but, i still having problems with itunes, and i was reading this: And it's fixed!: [Solved] iTunes Error 3194, Error 21 and Error 1013
and there is something interesting:
Other causes are to try to use a firmware version that Apple is no longer signing ie. 5.1.1.
that´s my ios, i´m not sure but according to this, i won´t be able to restore my ipod using this ios.....so i´d like to know if is safe to do jailbreak using ios 6...????
what do you think, what should i do...???
i don´t want to do a downgrade...!!!
---------- EDIT ----------
i found a solution to restore my ipod, i used redsnow following this video:
