I've just applied for a code signing certificate, and I'm wondering if they can be used for multiple apps that a single company releases?

I originally bought it to code sign an Adobe AIR Android app, but am wondering if the same cert could also cover...

- Adobe AIR iPhone app version of same above Android app
- Adobe AIR desktop APP (used as an admin app for the above two apps)

I guess my real question is - is the cert app specific, or does it just confirm the id the company?

Thanks for your help.
