Hi, I have tried 2 codes from another site that didn't work, I cannot risk locking the phone and am not sure what to do. I left the sim card in and input the codes from the home screen. Should I try to remove the sim card or using another sim card? It is locked into Vodaphone Australia. IMEI 358360008711042. Codes I have tried are: #pw+711930132036171+1# and #pw+084083106317227+7# I would be so appreciative of any advice. Thank You.
