Some developers have already begun to make the necessary changes. Last month, video-streaming provider Hulu updated its iOS app, dropping a link that allowed users to visit the company’s website to sign up for a paid subscription. Others, such as , have exploited a loophole: The login screen for the video-streaming app tells users to “Visit netflix.com to sign up” but does not provide a tappable link.

Other developers have not yet updated their apps as of this writing: Amazon’s ebook reader, for example, still prominently features a “Kindle Store” button; other e-readers such as Barnes & Noble’s app and Google’s app still have links to their own stores as well.

However, ’s sources can confirm that Apple has been working with various prominent developers to help them ensure their apps comply with the in-app content policies; expect to see updates to these apps in the near future.

Some less prominent apps will likely be pulled from the App Store as Apple starts to enforce the rule changes, but developers ought to be able to return to the store simply by updating their apps to comply.
