    Did you put your Iphone in DFU mode for Itunes to recognize, it should work. Then do the normal downgrade and you won't be able to use quickpwn or ireb to get out of error 1015, you have to downgrade Itunes 9.2 to < 9.1 for the tools to work or you can use another pc to get you out of error 1015. Quite a bit of work to do to downgrade from OS 4.0 to 3.1.2

    You said you have ios 4.0, you must have itunes 9.2 to sync. If you downgrade to 3.1.2, you will get error 1015, u need tools to get you out of the loop. Being on itunes 9.2, these tools don't work. These tools will work only if you have itunes less than version 9.1. So you either downgrade itunes or use another computer that does not have itunes 9.1 or 9.2, get it.

    ok i understand..... so, if i remove itunes right now and then i load the other one, will all of my music and stuff come back?

    well now im getting an error message saying that iTunes library could not be opened because it was made by a newer version of iTunes..... do you know a way around that?

    i had that problem too try to go to my music->itunes and save the Library.itl somewhere else and than after you downgrade you upgrade back to itunes 9.2 and copy the Lybrary back there .It worked fine for me!

    if you delete everything you`ll lose your back-up

    yea im tryin to do this myself, so as long as i got the 3.12 firmware/dfu mode/older itunes it should be cake?
    ios4 is not worth the issues on my iphone right now. basic phone functions slow and/or crashing is ridiculous.
