Just wanted to briefly share with you that Audible.com is now also giving into Apple’s much criticized app review guideline that forbids linking to a web-based shop from within your app:
11.13 Apps that link to external mechanisms for purchases or subscriptions to be used in the app, such as a “buy” button that goes to a web site to purchase a digital book, will be rejected
Audible just e-mailed their customers explaining their workaround. I am posting this because it is an example of how you can work around this annoying restriction.
