    Hi
    I have a 3GS and i jailbroke it years ago and it is currently on 3.1.2 but i have an app that tells it is one 3.1.3 because another app i wanted would not work without it being 3.1.3.

    Anyway, i would like to upgrade this to the latest 'safe' version 4.x or whatever it is but need some help understanding exactly what to do.

    The reason why i am wary is because i have downloaded a couple of apps from cydia - will these be lost in the upgrade?

    Currently i am on 3.1.3 (7E18) and when i go into cydia i can see that i have
    SHSH iOS 3.1, 3.1.2, 3.1.3, 4.0, 4.0.1, 4.1

    Can anyone let me know exactly what steps to follow and what i need to back up before i do it?

    Thanks

    If you upgrade it will restore your phone back to factory along with upgrading your OS, so yes all your cydia apps will be wiped out. You can re-jailbreak and get the apps back, but that is the only way. If you have paid cydia apps, you will be able to redownlaod them without repaying for them.

    If you have the blobs for 4.1 I would install that rather than 4.2.1. That way you can use greenpois0n or limera1n to jailbreak untethered. Unless of course you dont mind a tethered jailbreak, in which case you should just upgrade to 4.2.1.

    when i click on shift/update in itunes i can browse for a folder/file but when i unzip the 4.1 files there is nothing that i can use, the biggest file is a .dmg but i was under the impression that it is an .ispw file i am looking for (help)

    not sure but i think that the file i am trying to download is called iPhone2,1_4.1_8B117_Restore.zip

    Should the .zip just be replaced with .ipsw?

    hmm had to abort this, i think i am right in the above in that i should change the zip to ipsw but it seemed to go through the motions but then it came up with an error messge (3194 maybe) closed it too quickly

    Need some major help now getting this one sorted as i now have no idea

    Bumping up my own post here because i badly need help

    What i did was do a shift/restore and pointed it to a file i have on my desktop called iPhone2,1_4.1_8B117_Restore.ipsw but when i did it i got an error message

    Am i doing this correctly?

    Theres loads on information on Jailbreaking but not a lot on updating firmware on already jailbroken when the firmware isnt current.

    I believe that 4.1 is what i want

    Help please

    As of today, the 4.2.1 jailbreak is untethered, so you can just update to the latest OS and use greenpoison to jailbreak.
