I want to know if 1.1.3 (NOT OOTB) can be downgraded then jailbroken AND UNLOCKED with methods for previous versions.

Example: Can I downgrade to 1.1.1 and use the 1.1.1 method the jailbreak and unlock with anySIM.

Also I would like to know if I can downgrade from 1.1.3 (NOT OOTB) to 1.1.2 or 1.1.1 jailbreak and then use a StealthSIM or TurboSIM.
