I am pretty happy with the way my X is set up now in Froyo.
I did give some thought to doing the manual DL but saw that even though my phone is only 6 weeks old, I apparently don't have the latest (correct for DL) radio version. I saw something about SBFing back to the same version of Froyo I have now to do the DL and that made no sense at all to me nor did I know how to do the SBF (and I did sniff around awhile looking at that).
I admit I DNS but I presume there still may be some buggies in the current version that they may fix before the official OTA.
Yes, I'd like to at least try the new GB but for me, it's really fixing something that isn't broke (or broke much anyway).
Unless someone here talks me out of it, I'll probably just wait til Big Red knocks on the window of my phone with a hot steaming plate of GB.
