IOS7 text chat application with MultiTasking background and without APNS

Question

I want to create a chat application that will use a background service that will constantly request the selection of a specific client server.

This is a chat application.

I am an iOS app developer, but I do not own / control these servers.

I cannot share my APNS certificate with third parties who manage these servers.

Thus, the only way to implement it in iOS is to use the MultiTasking APIand classes NSURLSession.

Is it allowed to create chat applications that will not use APNSbut will use MultiTasking API?
