Do not hack the Vita.
Hacking the Vita to poo poo would be its final nail in it's coffin.

Do you actually want the Vita to be a success? Then don't hack it, giving the people the method to pirate games, and buy games for it.
The reason the PSP sucks so much in the West is because so many people hacked it, and as a result bought no games for it.

Also extracting a firmware file does not constitute finding any glitches, so i doubt this will lead anywhere.
