After last year's iPad and iBooks announcement, Apple made no real changes to its policy of accepting competing ereader applications from devices like the Kindle and Kobo, allowing users to read books purchased by the competing devices and apps. Now, Apple has slightly changed their policy, asking for a cut of the ebook sales when the content is purchased through an iOS application.
The news came after Apple rejected Sony's ereader app, which would have allowed purchases directly from the Sony Reader Store. Instead, according to a Sony exec, Apple now requires all in-app purchases to go through Apple. Both the Amazon Kindle app and Sony Reader app open a browser window to allow for book purchases, so opponents to Apple's new policy conclude that in-app purchases aren't taking place.
