I actually haven't tried anything yet. I won't have the phone for a few more days (ordered online).
Rooting isn't my only concern. I guess I worded my original post wrong. I would like the option of loading custom roms as well as rooted.
I also like the HTC programs (e-mail app, etc). As far as I know, I will need a Sense build to get all of that. This is the reason I would like to load a custom rom.
As far as SuperOneClick goes, I've tried to use it in the past on other phones. Its success is kind of hit or miss with me. Sometimes it works, sometimes it doesn't.
