Is there anyway to back up IOS 7.0.3? In case, say in the future, if I need to do a restore on the phone to get it serviced and it updates to a version that doesn't have a jailbreak. I can revert back to 7.0.3 and just re-jailbreak.



The reason I ask this is because that is how I lost my last jailbreak. I was on IOS 6.1.2 and had to restore it because I needed the internal speaker serviced and it updated to 6.1.4.
