Soon you will be able to downgrade iPhone Baseband

MuscleNerd has recently announced on Twitter, in addition to the recent developments, that you will soon be able to downgrade basebands. This is primarily for people who have upgraded to the 06.15.00 (iPad) baseband and want to restore to stock firmware. It may also enable accidental baseband updates to be undone so people stuck on basebands not supported by ultrasn0w can downgrade.
