Not registered new Kindle3 Special Offers act as normal kindle and have no adds.
It's good trade off for people not using the internet, to prevent having adds.
But not registering means also lack of some features as internal on device collections control which is as far as I know only way to put audiobooks into collections.
Does this hack or similar(big brother hack) prevent from putting by Amazon adds on your device and as a result have control over audiobooks? Or is there another way to contol audiobooks? I have failed with Calibre which I use only to create collections for books.
