I have an iphone 4 32 GB with 4.1 on it. IT is currently jailbroken and unlocked and I want to make sure I keep it that way, however I do want to restore. How can I restore it back to 4.1 and rejailbreak it step by step. All my SHSH are backed up with cydia. I am just not sure what the best way to do it is. Any help would be appreciated.
