Hi I just had my iohine unlocked by a seller in the UK and he told me that to complete the process I would need to use reset all settings so I can receive a message from the apple server. Though I need to know what reset all settings will do and if it will delete my app data or mess with my apps in anyway as I have some apps registered with my uk phone number that have few hundred dollars worth of credit I'm them and I won't be able to verify them again as I'm not in the uk.
