Ok, just jailbroke mine.

1). It makes it a little bit slower

2). http://youtu.be/HiJ6HoqISpE Is a very helpful tutorial and works perfect.

3). Bad things? The sources are illegal, but nobody ever gets in troubld.

4). I jailbroke mine to play pokemon and make graal tutorials with Display Recorder.

~ If you need a tutorial one how to get the gameboy on it, or do anything, I will make one, or youtube it =)
