Why do my xcode builds always go to the iPad simulator instead of the iPhone simulator?

I just installed the latest SDK from Apple so I can start learning iPhone / iPad app development. However, I'm having a stupid issue: all my builds get run in the iPad sim开发者_JAVA技巧ulator instead of the iPhone simulator, and I have no idea how to change it.

For now, the iPhone Simulator 3.2 SDK is iPad-only. Test using the iPhone Simulator 3.1.2 SDK

edit: as of the upcoming 4.2 SDK, the iPhone and iPad versions of iOS have been unified under a single SDK.

On your build selector dropdown, (where you select device or simulator), there's now a new option that lets you choose the "Active Executible." Choose "iPhone Simulator."
