    Default upgrading 3G 3.0 (huh..?)

    Hi guys,
    I tried to look for info on how to do this, but after hours I could not find an answer.

    I have a iphone 3G version 3.0, which HAS been jailbroken and unlocked before (I am not sure even how I did probably just followed really good instructions..)

    My trouble now is that there are a few aps that I really want to get that require version 3.1.3 at I need to upgrade from 3.0 to 3.1.3 (or later version if possible)

    So my question is, how do I do that, if anyone can explain it to be, or point me in the right direction, I would appreciate it.

    Also as a side question, do I have to backup all my music, will it be wiped off? I am not worried about the aps, but I would like to keep my music since I do not have it on my computer anymore

    Thank you in advance for the help

    3G is one of the easier ones to upgrade -- since the 3G doesn't use SHSH (until 4.0, anyway, and that's just soft SHSH), you can drop the phone to DFU mode and restore a custom OS to it with little trouble.

    I do not believe they released a PwnageTool for 3.1.3, I think the most recent they did was 3.1.2 for the 3G. As such, the easiest way is to download PwnageTool, create a custom 3.1.2 firmware, drop the 3G to DFU mode, restore the 3.1.2 firmware, then after that's successful and you copy your data over (don't recommend you set it up as a restore of your old phone, I'd recommend you extract the .db files from your iTunes backup and manually migrate them, but in either case), open Cydia and download the app that changes your reported FW version from 3.1.2 to 3.1.3.

    That should get you to 3.1.2 on your 3G, jailbroken (unlock if needed with ultrasn0w), with the device reporting OS 3.1.3, so you can run all the apps and iTunes will only ask you to upgrade to 4.0 (which I don't recommend on a 3G, unless you like waiting for things all the time.)

    Good luck!
