I was wondering if anyone knew how to downgrade an ipod touch 4g with the firmware of iOS 4.2.1 to the firmware of iOS 4.1? I had just recently purchase my ipod touch 4g and it came with the firmware iOS 4.2.1. I have also became very interested in jailbreaking it too and I have heard it is really hard to jailbreak an ipod touch with the firmware of iOS 4.2.1.
