I don't know about you guys, but I've been waiting for an update since 4.5 came out. I just wanted to share the news!
I would highly recommend you get ROM Manager - it makes backing up, restoring and managing all your ROMS very easy.
Worked great for me in Rom Manager (ClockworkMod). But then again I just rooted last night and downloaded BB v 0.4, then downloaded the theme this morning. So far loving it. Except I can't for the life of me read the battery icon.
