I have a iPhone 4 that I jail broke with jailbreakme.com on firmware 4.01. I have not updated it after all this time only for the fact I wasn't confident I'd understand or know how to do it. And I obviously DON'T want to lose my jailbreak EVER!!!!! When I look on my Cydia home page the SHSH: iOS 4.0.1, 4.0.2, 4.1, 4.2.1, 4.2~b3, 4.3, 4.3.3, 4.3.5, 5.0.1 Can anyone outline a brief description with steps on what to do in what order including backing up my phone so that I can get a more updated firmware without losing a jailbreak? Thank You in advance!!!!
