How do I declare device capabilities for this app?

Question

I have created an iOS 5.1 or later application for the iPhone 4S that requires a magnetometer, an accelerometer and also uses the Core Location framework

Apple's documentation is a bit confusing when it comes to declaring the device's required capabilities (confused over array or dictionary choice, entering YES/NO values, etc.) and I want to make sure I've added everything correctly.

This is what the relevant section of my info.plist looks like now :

Required Device Capabilities      Array    (4 items)
          item 0                  String   magnetometer
          item 1                  String   accelerometer
          item 2                  String   location-services
          item 3                  String   armv7 // was already added by default

(I have also added the name of the app and an appIcon in the appropriate fields)

Is the above information correct or do I need to add something more or change something?

Furthermore, the application was created to run on the iPhone 4S. But do the above requirements also let it run on other iPhone versions that I should include, or is the iOS 5.1 restriction limiting my app to only run on the iPhone 4S?

Should I also include somewhere that it can run on some version of iPod Touch or will it not run on one?

Thank you for your suggestions

The intent there is to provide required capabilities and not specific hardware (iPhone 4, iPod Touch, etc). As long as a device implements the required capabilities and has the minimum OS version that you are targeting then it will be able to run your app.
