I'm on 6.1.4 and have everything the way I want (programs, sms, etc). I have an iPhone on 6.1.2 that I intend to Jailbreak (and I won't reset it this time...). I read somewhere that if I backup the 6.1.4 phone to iTunes and modify some info file, that I can restore it to my 6.1.2 device. Is this true? Is it safe? Anyone have first hand experience with this? If I cannot restore, is there any way to save my messages or game save stuff?
