Still king of the hill when it comes to e-books despite the competition, Amazon and its Kindle brand of readers are making some new moves today on iOS with a brand new amazing Web app.

Confused by Apple's new subscription rules for e-book developers? Don't be. Here we give you a step-by-step look at what the new rules mean and how you can continue buying your favorite e-books from the popular Kindle app.

Apple's new subscription rules makes it the biggest loser. Here's why.

The Google Books app is once again available in the App Store. And it is now fully compliant with Apple’s new subscription policy.

Moments ago, Amazon updated its Kindle iOS application, making a variety of changes. First, Amazon removed the Kindle Store from the app, falling in-line with Apple's in-app policy (which the company appears to be enforcing now). Second, the Kindle app now supports newspapers and magazines (which obviously have to be purchased outside of the application). And third, users of the application can now share quotations from texts with friends, via Facebook and Twitter.

Apple’s new subscription rules are beginning to have an effect on iPad owners who use the iDevice to read books. While one e-book app has now been eliminated from the App Store, others have been radically changed to comply with the new rules. What’s the status of your favorite e-book reader app? Read on.

The free Google Books app is no longer available in the App Store. This news, which was first uncovered by 9 To 5 Mac, could suggest Apple is beginning to pull apps that violate the company’s new in-app purchase terms of service. Or perhaps Google pulled the app itself.

Apple's rumored in-app subscription deadline has passed, but Netflix and Amazon have refused to "amend" their apps via an update. As a result of this, Apple could refuse to accept future updates for both the Netflix and Kindle iOS applications.

The App Store could be without one of its most popular residents as soon as tonight. Amazon’s Kindle app could soon go away thanks to Apple’s new rules for in-app payment and subscriptions links, according to CNNMoney.
