iPhone running 3.1.2 JB want to upgrade?
I'm currently using the iPhone 3Gs on 3.1.2 firmware, it has been jailbroken using blackra1n.
I'm wonder what the best possible way it is to upgrade to 3.1.3? Because i prefer the untethereed jailbreak. I've been reading and tried and it says i cannot restore back to 3.1.2 because "This device isnt eligible..." i understand why, apple wont sign something
So now im wondering how i would upgeade? Would it be ok to download 3.1.3 and SHIFT+resotre it?
