Hey all, I've been trying to figure this out all day and still having some problems. I have an iPhone 4 running a jailbroken version of 4.3.3. I want to upgrade to the latest 5.x and preserve my JB and unlock. I tried using redsn0w first but that didn't work, when I tried to restore the custom IPSW iTunes says I'm not allowed to update to that release/version. Next I tried Absinthe but it says you have to have 5.1.1 installed prior to attempting the jailbreak and that Apple isn't signing 5.1.1 anymore, is there any way to get around this? Thanks for any help.
