iOS 7 is finally here. While many folks are busy playing around with it, they should also make sure they have their apps updated. Kindle 4.0 is not only fully compatible with iOS 7 but introduces collections. It makes categorizing books, docs, and documents on your iOS device easy.
The design is also flatter, which really should not surprise anyone considering that iOS 7 is quite a flat operating system. The translucency effects are a plus. The update also fixes performance and stability issues. Kindle 4.0 for iOS is available for download from the App Store.[via]
