Hi there, can someone help me please......... I would like to unlock my phone so it can use an O2 sim, it is currently on Orange The imei is 358399000666481. I have used a calculator and tried 4 different codes, however they are coming back as invalid. Do you need to take the sim card out? Also do you put the spaces in that are generated or is it just once continious 15 character string? Many thanks GOM
