Ive got one, big question. Im wondering since i can remember about downgrading my iphone 4 GSM with ios 7.1.2 to ios 6.1.3 or 5.1.1. Questions there: Am I able to do it without preinstalling any 3rd party apps like Cydia or Jaillbreak? I mean. Is it able to do the downgrade to te original IOS without redsnow and etc etc. I dont want jailbreak or cydia or sth like that on my phone.
Thanks in advice :)
