When I worked for Universal Uclick, we released the GoComics app all at the same time for iOS, Android, and Windows Phone. I worked on the iOS release until its launch, and we had the ear of its developer support team up until and well after its release. We even were able to get the app 'featured' in the App Store shortly after its release.

We didn't experience a cold shoulder at all from Apple after putting out the app for other platforms. But then again, that was just us.
