I have been trying to unlock my 6230i phone to use with the T-Mobile Network. But the codes arent working. Please help.
If you have tried over 5 codes, your phone is now hardlocked. It is very important that you realize every IMEI has its own unlock code. Cannot use a code given to someone else's IMEI to unlock your phone. There are various postal unlocking services in the world that will unlock /reflash your phone. Only professionals can unlock/reflash the phones as the equipment is about 500$ atleast.
