This website was started by Craig Whitmore (lennon@orcon.net.nz) as a method to change the APN on an iPhone which I had access to so I could use Mobile Data over the iPhone. When using a third party SIM Card in an iPhone, Apple had the idea of removing the option of changing the APN (depends on the Carrier ). Fortunately Apple supply instructions on how to make custom settings to change the APN and with this information I wrote this website.
