Got it in one. Thank you for making everyone's life easier by reading up on things! :-D dancedroidI have been lurking here reading up on everything, I think I'm pretty well set, if I understand correctly, rooting and then installing clockworkmod will also get me the clockwork recovery as well and I can backup the current default 2.2 software and then install a new theme if I want? If I want to go back I can just recover the backup I did and get back to default theme? Really only interested in the themes for right now.
If you want some more advice or help once you've rooted, click the link in my signature to a work-in-progress thread I've started. I hope it helps.
Thanks for the confirmation... Yea I have been reading up on your stuff too. Thanks for that information as well.
