    alright, so heres my situation. i have a 3g iphone but the lcd an touch screen are dameaged. so for the mean while i have this 8gb 2gen iphone. but, itunes says i need to activate the iphone each time i put my 3g sim card into the 2g iphone.
    ive read on other forums that the only way to do so is to downgrade to 2.0.

    my question is, if theres any way to use my 3g sim in my 2g iphone without activating it an not downgrading the firmware.
    why cant it just be used like when you pop your sim in a different 3g iphone?

    note:2g iphone is on 3.1.2 jailbroken firmware

    thanks

    Restore the 2G to the 3.1.2 firmware, jailbreak with blackra1n or redsn0w, unlock via bootneutor (through cydia). Insert sim card from 3G and you should be good to go.

    ok ssh to /private/var/root/Library/Lockdown/activation_records
    in this folder there should be a file with a 20 digit file name.
    probably starting with (8901****************.plst) this is the serial number of the sim you used to activate the iphone.if you open the file and edit the line that says
    ("IntegratedCircuitCardIdentity" = "8901***************")
    with the sim serial number of your tmo sim that you plan to use. Some old tmo sim only have 17 digits but the newer tmo sims have 20 digits,all the sims Ive looked at from att and tmo start with 8901.
