    I had my iphone 3g jail broken from when I bought it but hardly used the jail broken bit so thought I would just upgrade to the new software 4.0.1. The problem is it was also unlocked thru that so now I cant activate the phone as it says I dont have the correct sim card. Is there anything I can do? Like can I downgrade or anything?

    If you have your SHSH's backed up you can downgrade to a previous OS and re-jailbreak and unlock, if not, you have to wait for the new jailbreak to be released which by the talk of the web should be very very soon.

    *sigh* The iPhone 3G does NOT use SHSH's for firmwares prior to 4.0 and 4.0.1.

    With a proper version of iTunes you should be able to easily downgrade to 3.1.2 ( so you can hacktivate ) and create a custom firmware that is jailbroken and then install ultrasn0w to unlock the device.

    Indeed. I have up/downgraded my 3G many times. Only thing I noticed is that I downgraded from 4.0 and Cydia was changed to save blobs and I am on 3.1.2 and it says it has my blobs saved for 4.0.

    Try using sn0wbreeze to create a custom firmware that is already activated for your 3G. That might work. If not find a friend with a Mac and get them to create one for you using pwnage tool.

    I have used sn0wbreeze to create one using the 4.0 and the 3.1.2 softwares but I cant get what is creted onto my iphone? It just comes up after a minute or so there was an error restoring your iphone.
    Completly lost lol is there a step by step guide I can follow out there? I have tried finding one but cant get any for someone that has upgraded and found that they cant activate. The downgrading walkthroughs I cant seem to work either, the phone stays in restore mode and dont come out of it?

    iRecovery does not work, on either my pc (windows 7) or my laptop (XP) I install the libusb file and then run iRecovery but nothing happens, a black screen pops up for less than a second and goes away again? And after I restart my mouse or no other USB devices work so I have to do a system restore?
    Im completely lost here and have no phone for for 3 days! Can anyone help before I go mad lol

    Downgrade your version of iTunes first. Try going to 9.0 or something lower than that. You'll have to google around to find previous versions of iTunes. Once you've uninstalled your curent iTunes and installed the previous version, you SHOULD be able to get that "cooked" firmware onto your 3G

    You dont click irecovery like that to open it...

    Click start then run (or just type in the spot right above the start button on win7)then type "cmd" and push enter

    Then change the dierctory to where you saved irecovery by typing in without quotes "cd .." "cd .." (that goes up a folder in the command prompt)

    I had mine just saved on the c drive so for me it was "cd .." "cd .." (that got me from c\docandsettings to c

    Then cd irecovery

    then cd irecover_svn
    then ya type in the command box "irecovery" and it'll tell ya how to use it
