Hello all I am new here and I am after some help please.
I recently purchased a second hand 3g iphone from ebay.
Anyway received the phone put in a 02 3g sim card that I no is ok because I have used it in another phone.
But no matter what I do reset settings etc I can get no signal at all, so I decided to ring o2 and was totally blown away to find that the imei had been blacklisted and the previous owner had reported it lost a while back.
I asked them should I return it to o2 and they said no because the owner had received a new phone through insurance.
I went back on ebay to try and get a refund but what would you know the seller has gone.
Anyway my question is this I have read somewhere if I get another pcb and change it into my iphone this will put a different imei into phone then I just need to jailbreak phone and unlock it with blacksn0w.
If this is correct and will work by changing pcb board i have seen phones damaged etc on ebay and was thinking of buying one for spares and using its pcb board.
Any help would be very much appreciated

Hi gc1967,

I have a iPhone 3G 16GB Black phone. It is jailbroken and unlocked for use on any carrier. It is BLOCKED here in Australia but will work anywhere else. The phone is in perfect condition with no scratches.
