Most of the people reading this post right now are probably very familiar with this situation; you ask for something for Christmas, but the person who gets it for you isn't as technology-oriented as you, and they end up buying the wrong thing. This problem has never been more apparent this Christmas, because a lot of people who asked for an Android tablet received a Kindle Fire. And while a Kindle Fire technically does run Android, it's so modified that you can't even tell it's Android, except when you see the selection of apps.
Well, other people noticed this problem as well; hackers. And now, they have figured out a solution to the problem; put Android 4.0 (Ice Cream Sandwich) on your Kindle Fire! Hackers have indeed figured out how to do this, and they even posted a video below:
As you might be able to guess, the Kindle Fire and the Ice Cream Sandwich don't go perfectly together, just as putting an ice cream sandwich over a fire would make it melt. There's a lot of bugs that could ruin your Kindle Fire, and they haven't figured out a way to let the Kindle do audio and video playback. Nevertheless, if the situation I described is exactly what happened to you, I would wait around until the hack is improved, and then you'll have your wish.
