Building a Phone7 application that operates differently per mobile network operator

I have a product live on a network operators portal at the moment, it is integrated with the operators SMS/MMS messaging and billing interfaces. I would like to build a version of this application to run on Windows Phone 7 devices.

I'd like the application to run for all users but for users that happen to be on the network operator I've integrated with I'd like to offer them a better experience (direct operator billing and sending through the operators MMSC).

An alternative would be to limit the availability of the app to users with handsets on the operator (like the Android marketplaces that exist for the major cell network ope开发者_StackOverflow社区rators like Verizon and Sprint).

Is any of this possible on the Zune Marketplace for apps and/or on Phone 7 devices?

Thanks

To accomplish this I would suggest liasing with your network operator contacts.

You'll need access to the APIs which they have access to (and the public does not through the 3rd party SDK).

You may also want to ship an app with phones they supply also.
