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 canít activate the phone as it says I donít have the correct sim card. Is there anything I can do? Like can I downgrade or anything?

*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.

Thanks very much people, Iím hoping I can get this sorted. Iíll give you as much info as I can and Iím hoping you can help me out - I really have very little knowledge about this kind of thing.
I have the latest ITunes installed. My iphone if an 8gb 3g and Iím on o2 (UK). I got the phone on eBay about a year ago.
I have been looking around for help with this and I found this page (Downgrade iPhone 3G & 3GS From iOS 4 To 3.1.2). I do all it says but my phone sticks in recovery mode and I canít get it out of it Ė tried the program it says to use but it wonít open on my computer (windows 7)
Can anyone help me here?

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?
Iím 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

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
Thanks everyone so so much! I have it up and going again now, bit disappoint I canít update to the new software (I didnít know that was why my phone was jailbroken) but Iím more than happy to have it going again.
Thanks again everyone for your time and patience and if your every in Ireland message me and Iíll give you a pint or whatever you drink! :-)
