I hear on the Verizon iPhone you can't downgrade with or without SHSHs. I mean, technically you can with SHSHs but the phone will not activate. Therefor, you're forced back up to iOS 5 anyway.
Edit: you could try though. Use TinyUmbrella, open it and click Save SHSHs to pull them into TU, then start the TSS Server, then Shift+restore to 4.2.8. The restore will go through, the phone won't activate in iTunes though. At least that's what a couple of users around here have reported.

Won't work once u update to ios 5. Ur stuck if u have a vzw iPhone. I had my shsh blobs saved. The phone downgraded fine but would not activate. I tried different iTunes from 10 all the way to the newest one and even older ones. I tried jailbreaks to get past it. Still nothing. So until someone has a idea. Once u upgrade ur stuck.
