How to add new device to project?

[samurle]

Hello,

I'm a beginner to XCode 4, and I'm trying to add a new device to my project, however, I don't know how to do it.

For example, when I create a new project, in the project window, I can set the active build to:
- iOS Device
- iPad 4.3 Simulator
- iPhone 4.3 Simulator

However, for one of my older projects, "iPhone 4.3 Simulator" is missing. It only shows the other two devices.
How can I add it back to my project?

I've looked under "Project -> Edit Scheme", but I can't find anything about adding a new device.

Well, everyone must be on vacation, as this seemed like a relatively simple question to get answered.
Anyway, I found it.
