In this article on ebookmagazine.co.uk I read: In a statement posted on its ereader site, Sony said: “Unfortunately, with little notice, Apple changed the way it enforces its rules and this will prevent the current version of the Reader™ for iPhone® from being available in the app store. We opened a dialog with Apple to see if we can come up with an equitable resolution but reached an impasse at this time.
“We’re exploring other avenues to bring the Reader experience to Apple mobile devices. We know that many of you are eagerly awaiting the application and we appreciate your continued patience.”
I especially like the part about pursuing other avenues, hopefully, those avenues are legal. Apple’s behavior is very anti-competitive, hopefully it will blow up in their face.
