I have put together a small tutorial and some files to change the ".com" in safari on your iPhone to ".co.nz" or "com.au"
NOTE: This only works on iPhone's on version 1.1.2 or 1.1.3 - This means NO iPod Touch and no iPhone with firmware version 1.1.1 or lower.
I am by no means an expert. This was created with trial and error, Myself, Linka New Zealand Limited or ModMyiFone.com will NOT be held responsible if you brick your iPhone during this mod.

Now before you comment on the fact that you have to register to view the tutorial see below:
I am unable to make downloads available to members only so I have made the tutorial available to members only (which contains the downloads). I have done this to stop a high server load causing the site to go down.
Registering takes all of a minute of your time. Figuring out how to do this took me a lot longer. I have no problem if you don't want to register, you just don't get access to the files. You can always do it yourself, but it would be quicker to register.
