Only downgrade from 2.30.03?

Can one downgrade from other baseband?(with bl5.8) Or one can only downgrade from 2.30.03.

Cause I saw on Geohot's blog that one need other patch(cert) to downgrade from other baseband firmware.

However when I compared the .fls file in this package with the original took from 2.2.1 ramdisk, it is the same.

Maybe the patch is done by PHaseBanDowngrader on the fly?

P.S. : I myself has 2.28.00 with bl5.9, just out of curiosity.
