The Kindle Fire has a good reputation among developers for being hackable and months after release, people were able to add loads of restricted apps, including YouTube, Google Maps, Google Talk, Gmail and others. Some even managed to port Jelly Bean to the tablet with some success, replacing the heavily-customized build of Gingerbread (Android 2.3).
Although Amazon keeps quiet, experts believe that the upcoming Kindle Fire HD will be much harder to crack as evidenced by TI’s security features and signed bootloader. Amazon wants to confine all Kindle Fire tablets in its walled garden and selling a completely locked down device would be in its advantage. After all, Amazon wants consumers to use Kindle Fire as a way to purchase and run its digital products. This is why Kindle Fire is priced so low and consumers don’t get the usual Google experience, especially not an access to the Google Play store.
