I've read a lot about 4.6 BL and somewhere it said that the H/W method would be replicated by the S/W method. What I understood (maybe I'm completely wrong) is that the BL has to be patched somehow in order to be able to patch the BB. Is it true? But a question comes: the S/W unlock will downgrade the BL or it will unlock 4.6 itself? I'm asking this because the "official" H/W unlock for 1.1.2 OTB downgrades the BL so it can be unlocked via normal methods.
