Hello!! I have a 3gs (3.1.3 / 05.12.01) with jailbreak and unlock. I wish to upgrade to 4.1 but my cydia says I have SHSH IOS 4.2.1. This means I can`t go for 4.1 on pwnagetool? I have to go to 4.2.1?? My issue is that I really need the unlock part, so I don`t know if you recommend me to upgrade to 4.2.1 or if you know a way to upgrade and still get the unlock.. (should I make a custom firmware on pwnagetool for 4.2.1?) I have a general idea but I really don't know what to do, if someone can help me with the steps or guide to accomplish the upgrade, jb and unlock I will REALLY appreciate it!!!
