Hi all I want to update my iPod as above so that I can perform an untethered jailbreak using evasi0n. I know that 6.1.3 isn't jailbreakable (untethered) so have downloaded iOS 6.1.2 which I believe is an untethered solution. I just wanted to ask if someone could advise me how I can install this without iTunes prompting that it can't verify the ipsw. I remember that this used to be done by modifying the iTunes file to point at cydia's servers but it has been a few years since I did a jailbreak and wanted to check if there is now different methods around? Thanks in advance!
