Blackra1n is pretty much obsolete. Also, it wouldn't really make sense to release the untethered userland jailbreak as jailbreakme 3.0, because if we want to use the bootrom exploit too, it would mean that one would have to jailbreak tethered with redsn0w first, and then untether with jailbreakme 3.0 (unless they incorporate the bootrom exploit in the new jailbreak)
