Someone already tried this new sbf version of 2.2? Follow the link: and-developers.com/sbf:defy

That's weird. I just flashed my Defy with this firmware and all works fine. But when it rebooted, all my settings, apps, wallpapers, everything still there.
In this version almost motoblur crap was removed. My Defy is running very fast now.
