I want to change this:
//
// ViewController.h
// MyApp
//
// Created by _username on 12-04-05.
// Copyright _company_name. All rights reserved.
//
And I tried: http://macdevelopertips.com/xcode/change-company-name-in-xcode.html and it didn't work.
I also tried this: http://iosdevelopertips.com/xcode/change-company-name-from-within-xcode-on-a-per-project-basis.html but it did not exist in Xcode 4.
I'm using Xcode 4.2
go to System preferences -> users and groups -> click on your username
On that page there should be a button saying Open...
click that and change that record in your contacts. When you create a new class it should get the information from that record!
