Best bet is ring your network depending on there policy they might charge but they send your imei number to apple and will unlock your phone permanent software unlock is ok but if you upgrade firmware by accident it's lost again.
sorry i am not the original owner bought it as i was going to unlock but did not when found out it mucks up the gps and unlocking through network costs £20 and if i can unlock for free will use it for a few months untill my own phone is up for upgrade
