Ok, so I am not a hacker or an iPhone expert. I have a dilemma and am wanting to get some advice. I own two iphone 5's. One is jail broken and running iOS 6.1.2. The other is running iOS 6.1.3 because it was accidentally updated and now cannot be jail broken or downgraded back to 6.1.2. My question is this- I NEED the iPhone that is running 6.1.3 to be jail broken so I can install certain software on it, whereas the iPhone that is currently jail broken doesn't really need to be able to run cydia. So.....since I have no way to jailbreak the other phone could I switch motherboard and SIM cards or any other components between the two devices in order to switch the operating systems they are running? I don't know if this is even possible or if it would work, but it it would I am capable of switching them as I have taken apart and repaired several iPhones. Can someone please help me and let me know if I'm way off base here or if anything can be done in this situation? Thank you.
