so i used to have an 3gs iphone 3.1.2 firmware and jailbreak it with blackra1n, but one time i turn off and when i turn it back on it make me restore and upgrade to 3.1.3 (connect to itune) which i don't want to, and i'm jailbreak just to use with other phone carrier.
( The question i have here it, is there a way for me to get back to 3.1.2 jailbreak just like before i turn it off? some people said i just have to using blackra1n against when i'm in recovery mode, but i'm just want to make sure, because i'm about to get a new 1)
