Well now I'm conflicted. It would be nice to update straight to official Mango without losing anything. But I have a feeling I'll probably roll back to Nodo because I want to get my Interop homebrew apps working on Mango, and currently the only way to do that for HTC phones is to roll back to Nodo. I've done a hard reset before and it wasn't too painful aside from reinstalling apps, and rolling back wouldn't even be that bad because I would only lose the newer stuff.
Decisions, decisions...
