Carrier settings file
How can I modify the carrier settings file. I have an unlocked (bought that way from the Apple shop) 3GS with a Hutchison_au.ipcc carrier settings file. This sets up a key on the phone keypad to dial their voicemail when it's pressed. I don't use voicemail (when I want to talk to a computer, I'll use a keyboard) and worse they charge 70 cents every time I hit it and I've got fat fingers. Help...
