iOS 5 to iOS 4.3.3 then JB

Has anyone upgraded an iPhone 4 to iOS 5, then back down to 4.3.3 and been able to use redsnow to jailbreak it untethered? I have a phone I need to do this on but since the bootrom was upgraded will this interfere?

Yes!

I've done exactly that with no problems. Then I upgraded to ios5 again!! Fickle.

Done this myself, no issues at all. Just do a DFU restore to downgrade

Yeah It Works.
Make Sure you have Clean Hosts file and Wifi Sync in Uninstalled while restoring your iPhone.
