Got "backup plan" for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you

Users having iPhone 4, iPhone 3GS (new bootrom) iPod touch 3G and iPod touch 4G will now be able to boot untethered now, there will be no need to connect to your computer on every reboot.This method also uses iOS 4.2b3 (Beta 3) SHSH blobs which Cydia was saving for all iOS devices last month.

(It’s a “backup plan” because comex is working on a more extensible one, but this method is also generalizable)
