The Windows PC is my main computer, so I’ll assume you are barely familiar with the Mac interface (maybe you’re moving from the PC to the Mac just for building apps, like me). So I think you’ll find these steps easy to follow. At this time, there are no screen shots (sorry). I assume you already have Xcode 4 installed. I’m not going to go into provisional profiles here; I’m going to assume you will take care of that on your own.
