Apple Moves to Tighten Control of App Store

Apple is further tightening its control of the App Store. The company has told some applications developers, including Sony, that they can no longer sell content, like e-books, within their apps, or let customers have access to purchases they have made outside the App Store.

Apple rejected Sony’s iPhone application, which would have let people buy and read e-books bought from the Sony Reader Store. Apple told Sony that from now on, all in-app purchases would have to go through Apple, said Steve Haber, president of Sony’s digital reading division. The move could affect companies like Amazon.com and others that sell e-book readers that compete with Apple’s iPad tablet and offer free mobile apps so customers can read their e-book purchases on other devices. An iPad owner, for instance, has not needed to own a Kindle to read Kindle books bought from Amazon. That may now change.
