i just skimmed through it. i guess i should have phrased my question a little differently. here's my understanding:
you do not need a currently jailbroken device. you use TU and create a custom firmware with the shsh blobs and save them to your computer to use when the JB is released. is that correct? i just want to make sure i'm understanding things properly so i don't mess anything up.
Nope, SHSH's are only for downgrading or re-restore, nothing to do with the JB.
