Australian Phones aer the most difficult ones I have come across. There seems to be a general difficulty with Australia. Each phone is allowed only a few tries before it is hard locked. 3 to 5 tries. It still works but you will need a cable and a thing-a-me-giggy to unlock it. It will STILL WORK on the original Network. I would like to see if I can figure out the right code. I can only think of 4 or 5 ways. The problem is that people who have requested codes have not always replied after getting the codes. Remember that each phone uses a unique code. These Codes are based on the Network codes and a security code. That combination of codes is what we need to calculate the code. It is important that I know if the phone returns an error message when a code is entered. I can give you a code that I would expect to work. It may not work however. If you would like to try a free solution you can try the Code I give you or you can take it to your local Phone repair professional and have it done. JG
