It's all scary, but if you can follow directions, it's easy. This is a food phone to have to root for your first time, because there is not a super easy one click way. You'll be a lot more knowledgeable than say a person that rooted an original evo.
I would say take a few days, read the guides, get the things downloaded your gonna need, and do it. Youll probably need a few hours, and a xanax or 2. Start with Mr Smith's guide,then gotto the forum that can't be mentioned an read through those guides. You probably won't understand what a lot of things are, but I believe AC has an android dictionary to help with that.
If all else fails, come here and ask, we won't banish you or anything.
