For Australia Telstra 2600 ONLY

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.
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 for the 2600 have not 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 figure out.
I need 5 owners of 2600 phones on Telstra Australia that are willing to reply if and when it works. If you have posted a request and are willing, reply to this with "I will" and I will look for your INFO in the Thread.
