I received my replacement refurb :L today because of a bricked froyo update on my less-than-2-month-old-brand-new DX.
I activated it and did the update over wifi. I then did a factory reset because it never really was "fresh" - in other words, I was never prompted to log in or create a google account from the first time I turned it on.
After the factory reset, it booted fine, I logged into my gmail account and all apps synced back.
All is well now. Pot luck? No clue, but so far I'm good.
Either way you slice it, there's no question something is funked with this release. I hope Moto straightens it out quickly..
Seriously, isn't the main purpose of locking down this device (for moto anyway) to keep it stable? Meh.
