Testing iPhone-only app on iPad without zooming?

Question

My case is:

• I am building an iPhone-only app.
• My test devices are iPhone 4s and iPad 4.
• I would like to support iPhone 5/5c/5s screen sizes, but I don't have the actual devices.
• Can I use the iPad to test the UI for iPhone 5/5c/5s screen size, but without the automatic zoom of the app - simply taking only the 640×1136?

Thanks.

No, the iPad has not setting to allow this, neither did Apple release any API to do this.
