I've updated to the latest iOS for the 4G iPod Touch and now want to rehack it. I'm preferably looking for it to be entirely untethered. It will either have to be a jailbreak for iPod Touch 4G v6.1.3 that's untethered or a downgrade to something like iOS v.6.1.2 but without SHSH blobs because I don't have any of those. I could deal with a semi-tethered/untethered jailbreak, as long as someone could explain to me how that extent works. I just basically want to know if at my position I'm entirely screwed or not entirely screwed if I want an untethered jailbreak for v6.1.3 4G iPod Touch without SHSH blobs. Thanks!
