Hi guys strange one here...

had an i phone before and jailbroke and and unlocked it fine...

now my new one which is the 3g on 3.0 had been jailbroken with redsnow and unlocked with untrasnow tried all the others this is the only one that seems to work but the only way to get it to recognise my sim is to put it in my nokia and then straigfht back into the i phone this is the only way the i phone picks up the signal on my orange network but even then if i lose signal or put it on airplane mode it wont get the signal back please help as it isnt really making it usable
