This is optimized for the HTC EVO 4g, but can easily be modified for other phone models.
EDIT: Was bored as hell the other day, so I decided to create a "do a barrel roll" boot animation. Included are 2 audio files, one with a 5 second pause because the animation lags a little for me at the beginning, and one without the lag.
And if you like them/use them, please hit the thank button. It will encourage me to keep uploading whatever I do for you all, (even if making a boot animation is pretty easy, I'd still appreciate it..).
