    Hmmmmmm, interesting. I am just wondering how did you put on OS 4.0 on a 2G which is the first generation iphone. I thought the highest OS you can install is up to 3.1.3.

    Are you sure it is not a 3G, does it have a white or Black or Silver backing ?

    From the look of it , it is a 3G iphone.

    I am not trying to be nasty, if you found the phone , that is fine but if you stole it then that isn't good.

    Its definitely not a 2G.

    Do you have a Compass icon on it, if not then it is a 3G,

    To jailbreak a 3G at iOS 4.0 run Redsn0w 0.9.5b5, download the 3G 4.0 ipsw .
    and then unlock with Ultrasn0w 0.9.3 from Cydia.

    Edit : what was your question again, are you asking about downgrading ?

    uh, i want to downgrade(jailbreak) it back to 3.12 (or something like that) b/c i heard that it was alot faster better etc. I also want to unlock it so i can use w/ tmobile.

    where would the "compass icon" be?

    If you are already jailbroken at iOS 4.0, then it is easy, just put your iphone in Recovery mode and restore to a cfw of 3.1.2 or 3.1.3.

    If you are not jailbroken at iOS 4.0, then put your Iphone in DFU mode and you have to restore to stock 3.1.2 or 3.1.3 fw. You will encounter 1015, use ireb 3.1.2 to get out of this loop. Once booted in Emergency Screen, then you can use your preferred tool to jailbreak.

    Home screen, first page by default. Another way to check if you have a 3GS is by opening the official camera app, then check to see if you can record video using a slider in the bottom righthand corner, if there is no slider, it is most certainly a 3G.
    If I somehow helped you, press thanks

    zomg this is soo complicated T_T. I'v gotten all the way past the restore now on the emergency call screen; now what? I used redsnow (.9.5b5)but idk what to do. do i put the stock firmware when it asks me to browse for one or do i put a custom one??

    Hahaha, you didn't think that there is so much to it, there will be more only if you encounter problems but I think you can make it.
    When running Redsn0w 0.9.5b5 browse to stock 4.0 and do the jailbreak from your already updated either to 4.0 or 4.0.1. If you don't want multitask, uncheck it, if you want to activate your iphone, check the activate box

    Oh! If Cydia asks you if you want to make my life easier , say YES, because from now on OS 4.0 and above in order to downgrade you need shsh blogs on all 3G but you can bypass with Custom Firmware for future updates.
    Only OS <4.0 does not need shsh blogs.

    ...confused?
    this is what am at now:
    Iphone is right now at 3.1.3
    i used the snowbreeze to <i>try</i> and jailbreak/unlock
    but i keep on getting the 1600 error. Iv tried using the ireb to get around the errors but that hasnt worked.

    right now am going downgrade it even futhur to the 3.1.2 stock firmware and see if that works. (my phone has the 5.12 somthing baseband/modem ver.; is that a problem?)

    if you can give any tips/help id greatly appreciate it. As per the 4.0; am not really intrested in 4.0. idk, i think the 3.1.2 would be alot faster than the recent one; more stable also.

    edit: the snowbreeze that am using (1.4); i make the ispw and everything, but on itunes when i restore it; it just hangs on the "preparing iphone for restore" then it just gives me an error. help?

    edit: when i try restoring it in dfu mode; i get the 1600 error.

    nm guize; i got blackrain and that solved everything for me x) ty for all your help though
