Certificates, application ID, and provisioning profile

To send an iPhone application to the App Store, we need to create certificates, an application identifier and a Provisioning Profile.

I often get confused with these things (even after reading Apple's documentation at http://developer.apple.com/library/ios/#documentation/ToolsLanguages/Conceptual/DevPortalGuide/Introduction/Introduction.html#//apple_ref/doc/uid/ TP40011159-CH1-SW1 )

So can someone please explain these things to me in simple words.

  • Is it possible to use the same certificate for several applications (and for dev / distribution)?
  • I also assume that the application identifier is unique for each application. But can the same application identifier be used as for dev / distribution?
  • For the Provisioning Profile, I think we need to create 1 for Dev / distribution. Correctly?

Please explain this in plain language. Thank.

1. Is it possible to use the same certificate for several applications (and for dev / distribution)? No, distribution certificates cannot be used for development, especially the App Store profile, which can only be used to send applications.

2. I also assume that the application identifier is unique for each application. But can the same application identifier be used as for dev / distribution?
