New to Android INcredible 2

[jarvis86]

I just got an Incredible 2 and it is running 2.3.4 (gingerbread,right), I would like to downgrade to 2.2 (froyo,right) so i can root it. how can i do this? Or can i root without downgrading? are there any apps that will do this? i need easy instructions and the easiest way possible, as i am new to the world of android.
