A few questions about Mango and Homebrew

[rodney0905]

I installed the 7720 Mango build. I believe this is the RTM , is this correct? So there should be no bugs and is official?

Homebrew was super easy with WebOS. I am a little confused with WP7. Is Homebrew available with Mango? Everything I see is geared toward Samsung devices or is outdated.

I want to be able to change theme colors, registry edits, install homebrew apps but I can not find anything that is up to date.
