Hello, I'm attempting in upgrading my jailbroken iphone 3gs which is on firmware 3.1.3, and I have an older version of itunes. and I have my SHSH files for: 4.0/4.0.1. I want to upgrade to 4.0.1 So basically what I'm going to do is to first edit my host files and add this to the end (18.104.22.168 gs.apple.com) Then put device in DFU mode and restore manually. My question is: What are the order of the steps I need to do? I meant, do I download the latest version of iTunes first? or do I do the things I listed then download the itunes latest version? one more thing: I heard cydia is down or upgrading now, so shall I go ahead and jailbreak it after upgrading the iOS or will it crash or smth? Thanks in advance.
