I suspect the answer is no, but I have to ask. I have a jailbroken iPad 4 (64 Gig wifi + AT&T 3G) running 6.1.2. I have some program leak that is killing my battery. I've had this before and the only way to fix it was to restore to factory settings. I don't want to lose my JB and I know that 6.1.3 can not be jailbroken. Is there a way to restore to 6.1.2?
