If all depends on the kind of SBF that you flashed. If you have flashed a FULL sbf then you can't downgrade most likely. If you flashed a FIXED sbf then downgrading shouldn't be a problem.
I made the same mistake in the beginning but luckily I only flashed a FULL 2.2 sbf which is stable. For now I always start from this rom, get root on my phone using superoneclick, install 2ndinit, reboot into 2ndinit recovery (volume down when led turns blue) and I install the nandroid backup that I placed on My SD card using "install from zip".
It would help if you gave some more info on which sbf you flashed?
