    I want to downgrade my iphone from 1.1.2 to 1.0.2 but when I use jailbrake than I have no connection whit my phone. When I use Itunes it works but Itunes restore 1.1.2 and not 1.0.2 or 1.1.1 (I get a error 1)

    How can I fix this connection problem?

    Error 1 means that restore didnt even start. You didnt put your phone into DFU mode. If you do it right the screen will be totally blank and the pc will recognize a phone in recovery mode. Again, if your screen has anything on it whatsoever or the phone even looks turned on, you did it wrong:

    1) Attach the phone to the pc
    2) Turn the phone off
    3) Hold power and home together for *exactly* 10 seconds
    4) Release power but keep holding home until the pc beeps as a USB device is recognized.

    At no point will the display come on. Now your restore should work.
