    Hi everyone

    basically i got a iphone 3g 8gb which was working fine on 3.1.3 jailbroken.

    So without reading I assumed 4.0.1 would be better so I upgraded (manually via Shift+restore in itunes) all went well and i hacktivated/JB it then I read about speed issues with the 3g and im sure mine was slower!

    So decided to downgrade (didnt SSH or anything previously!) so I managed to downgrade it back to 3.1.3 but now the problem is I cant JB it with spirit as it needs to be activated first! (I dont have an 02 simcard, will any 02 sim work?)

    I want to Jailbreak it then unlock it so I can use it on T-mobile! am I right in thinking this is impossible on 3.1.3?

    what can I do? I attempted to restore back to 4.0.1 (as at least I could use the phone) but Itunes was throwing up all kinds of errors!

    Please help

    can anyone confirm 3.1.3 is NOT unlockable? therefore this could be the reason it recognises the t-mobile sim but wont make calls?

    Use redsn0w 0.9.4 and the 3.1.2 FW. It will hacktivate and jailbreak it. Once that is done go in cydia and install ultrasn0w. As far as the call forwarding there is an option to disable it in the settings app

    If it helps at all heres the details from the settings page -

    version 3.1.3 (7E18)
    carrier 5.1
    Model MB489B
    Modem Fw 05.13.04

    It seems strange that it has signal and allows T-mobile to be displayed as the carrier etc, but just cant txt/call out!?? If an Iphone is blocked/disabled does it have these effects?
